Harrison Ford’s Apple TV Series Officially Expands Season 4 Cast

Published Nov 15, 2026, 6:00 PM EST

Ryan O'Rourke is a Senior News Writer at Collider with a specific interest in all things adult animation, video game adaptations, and the work of Mike Flanagan. He is also an experienced baseball writer with over six years of articles between multiple outlets, most notably FanSided's CubbiesCrib. Whether it's taking in a baseball game, a new season of Futurama or Castlevania: Nocturne, or playing the latest From Software title, he is always finding ways to show his fandom. When it comes to gaming and anything that takes inspiration from it, he is deeply opinionated on what's going on. Outside of entertainment, he's a graduate of Eureka College with a Bachelor's in Communication where he honed his craft as a writer. Between The IV Leader at Illinois Valley Community College and The Pegasus at Eureka, he spent the majority of his college career publishing articles on everything from politics to campus happenings and, of course, entertainment for the student body. Those principles he learned covering the 2020 election, Palestine, and so much more are brought here to Collider, where he has gleefully written on everything from the SAG-AFTRA and WGA strikes to Nathan Lane baby-birding sewer boys.

Until 2022, Harrison Ford never had a regular role on a television series, remaining best known for his cinematic efforts from Star Wars to Indiana Jones, and his Oscar-nominated turn in Witness. Yet, he's now been at the center of two massive and very different shows from two of the industry's most prolific creators. He first joined Taylor Sheridan's wider Yellowstone universe with the prequel Western 1923 at Paramount+, which came to an emotional close last year. Over on Apple TV, meanwhile, he's become part of the beating heart of one of Bill Lawrence's most acclaimed modern comedy-dramas. The beloved star is now about to have some new company to work with heading into Season 4, too.

Deadline exclusively reported that Shrinking has added three more new names to an already vastly expanded cast. Dyllón Burnside, Jillian Bell, and Addie Weyrich will all join fellow newcomers Christian Slater, Karen Gillan, and Judith Light in recurring roles as they step into the offices of Jimmy Laird and Dr. Paul Rhoades in Season 4. At this point, nothing is known about their respective characters, though they'll factor into the new storyline that Lawrence and fellow co-creators Jason Segel and Brett Goldstein have planned after Season 3 wrapped up Jimmy's arc of grief and moving on. Segel, Ford, Jessica Williams, Christa Miller, Luke Tennie, Michael Urie, Lukita Maxwell, and Ted McGinley.

Burnside is a regular Ryan Murphy collaborator, having notably starred in FX's Emmy-winning LGBTQ+ epic Pose and enjoyed appearances in Monster: The Jeffrey Dahmer Story and American Horror Story. The Emmy-nominated Bell, meanwhile, brings a wealth of comedic experience across the big and small screen, from 22 Jump Street to SuperMansion, Workaholics, and much more. Last year, she also made her feature directorial debut, helming the Chloe Fineman-led raunchy comedy Summer of 69 to strong reviews from critics. Weyrich rounds out the trio with a resume that includes the Keanu Reeves angel movie Good Fortune and the Diane Keaton-led comedy Mack & Rita.

Question 01 of 08APPROACH

01 A critical patient comes through the door. What is your first instinct? Medicine under pressure reveals who you really are.

AStay completely present. Block everything else out and work it step by step, right now. BTriage fast and delegate. Get the right people on the right problems immediately. CTrust my gut and move. I work best when I stop overthinking and just act. DAsk the question everyone else is ignoring. What is the thing that does not fit? ETake a breath, make a joke to cut the tension, then get to work. Panic helps nobody.

Question 02 of 08MOTIVATION

02 Why did you go into medicine in the first place? The honest answer says more about you than the one you would give in an interview.

ABecause I wanted to be where it matters most, right at the edge, when a life is on the line. BBecause I wanted to help people, one patient at a time, in a system that makes it hard. CBecause I was drawn to the intensity of it: the stakes, the drama, the feeling of being fully alive. DBecause medicine is the most interesting puzzle there is, and I needed a problem worth solving. EBecause I wanted to make a difference, and also, honestly, I did not know what else to do.

Question 03 of 08COLLEAGUES

03 What do you want most from the people you work with? Who you want beside you under pressure is who you are.

ACompetence and calm. I need people who do not fall apart when things get bad. BTrust and reliability. When I pass something off I want to know it is handled. CConnection. I want colleagues who become family, even when that gets complicated. DIntelligence and the willingness to be challenged. People who just agree with me are useless. EFriendship. People I like spending twelve hours a day with, because those hours are happening anyway.

Question 04 of 08LOSS

04 You lose a patient you fought hard to save. How do you carry it? Every doctor who has worked a long shift has had to answer this one.

AI carry it. All of it. I do not look for ways to put it down, because that weight is part of doing this honestly. BI process it and move. You have to, or the next patient pays for the one you just lost. CI feel it deeply and lean on the people around me. Nobody is supposed to handle that alone. DI go back over every decision, not to punish myself, but because I need to know what I missed. EI grieve it, find something unrelated to laugh about, and try to be kind to myself. Imperfectly.

Question 05 of 08STYLE

05 How would your colleagues describe the way you work? Your reputation on the floor is usually more accurate than your self-image.

AIntense and completely present. No small talk during a shift, but exactly who you want there. BSteady and dependable. Not the flashiest in the room, but never the one who drops something. CPassionate and occasionally chaotic. Brilliant on the hard cases, prone to drama everywhere else. DBrilliant and difficult. Right more often than anyone else, and everyone knows it, including me. EWarm and self-deprecating. Not the most intimidating presence, but good at this and easy to like.

Question 06 of 08RULES

06 How do you feel about hospital protocol and procedure? Every institution has rules. What you do with them is a choice.

AProtocol is the floor, not the ceiling. I follow it until the patient needs something it cannot give. BI respect it. The system is broken in places, but the structure exists for a reason and I work inside it. CI follow it until my instincts say otherwise, and my instincts are usually right, even when they cause trouble. DRules are for people who have not thought hard enough about when to break them. EI try to follow it and mostly do, with a few memorable exceptions that still come up in meetings.

Question 07 of 08TOLL

07 What does this job cost you personally? Nobody works in medicine without paying a price. What is yours?

AEverything outside these walls. I gave this job my full attention and the rest of my life went around it. BMy idealism, mostly. I came in believing the system could be fixed and I made a complicated peace with that. CStability. My personal life has been as chaotic as the OR, and that is not entirely a coincidence. DMy relationships. I am not easy to know, and the people who tried would probably agree. EMy sense of gravity. I use humor as a coping mechanism, which not everyone appreciates in a hospital.

Question 08 of 08PURPOSE

08 At the end of a long shift, what keeps you coming back? The answer to this one is the most honest thing about you.

AThe fact that it is real. Nothing else I could be doing would matter this much, right now, today. BThe patients. Individual human beings who needed something and got it because I was there. CThe people I work with. I have walked through impossible things with them and I would do it again. DThe next unsolved case. There is always another puzzle, and I am not done yet. EBecause despite the exhaustion, the loss and the absurdity of it, I love this job.

Assignment madeYou belong in

PTMC · Admitted The Pitt Pittsburgh Trauma Medical Center This ward asks whether you can stay in the room for the whole shift, and come back tomorrow.

You are built for the most unsparing version of emergency medicine television has shown, the one that puts you inside a single long shift and does not let you look away. You need your work to be real rather than romanticized, and you find your purpose inside the work itself rather than in the chaos around it. You have made peace with a job that takes from you constantly and gives back in ways that are harder to name. What this ward asks of you

• Meaning over drama, honesty over aesthetics.
• The discipline to stay present when the department is at its worst.
• A tolerance for weight that does not get put down at the end of the day.

From the Collider file

• Each episode covers roughly one hour of the same emergency-department shift, in order.
• Noah Wyle has now won the lead drama actor Emmy for it twice, in 2025 and again in 2026.
• It reunites the ER team of Wyle, John Wells and R. Scott Gemmill, thirty years on.

Fully present No romance Built to endure

CGH · Admitted ER County General Hospital, Chicago This ward asks whether you can hold the line long enough for the next person to take it.

You are the one who keeps the whole floor moving. Not the most brilliant in the room, possibly the most essential. You show up, do the work, absorb the losses and come back the next day without needing the job to be anything other than what it is. You care about patients as individual people rather than as cases to solve or dramas to live inside, and you believe in the system even on the days it fails you. What this ward asks of you

• Reliability above brilliance, every single shift.
• Faith in a structure that is visibly imperfect.
• The stamina to treat the hundredth patient like the first.

From the Collider file

• Fifteen seasons and 331 episodes, from 1994 to 2009, created by Michael Crichton.
• It holds the record for the most Emmy nominations of any drama series, with 124.
• George Clooney, Julianna Margulies and Noah Wyle all broke out of County General.

Shows up Endurance Patient first

GSM · Admitted Grey's Anatomy Grey Sloan Memorial, Seattle This ward asks whether you can do the work with your whole self in the room.

You came to medicine with everything you have, your ambition, your feelings, your relationships and your history, and you have never quite managed to leave any of it at the door. You form deep attachments to the people you work with, and your personal and professional lives stay permanently, chaotically tangled. That tangle drives both your worst disasters and your most remarkable saves, because you understand that extraordinary medicine often happens where clinical skill meets human connection. What this ward asks of you

• A willingness to feel all of it rather than seal any of it off.
• Colleagues who become family, with everything that costs.
• Comfort with mess, in the OR and everywhere else.

From the Collider file

• Shonda Rhimes' series passed ER to become the longest-running primetime medical drama on US television.
• It is on season 22, with ABC having already renewed it for a twenty-third.
• Ellen Pompeo has played Meredith Grey across three decades of television.

Feels everything Found family Beautifully messy

PPTH · Admitted House Princeton-Plainsboro Teaching Hospital This ward asks whether you can be right when everyone in the room needs you to be wrong.

You are drawn to the problem above everything: the symptom that does not fit, the diagnosis hiding underneath the obvious one. The patient as a person is not your first motivation, though you are capable of caring more than you would admit. You work best when the stakes are highest and the standard answer is wrong. Princeton-Plainsboro exists to house one extraordinary and impossible mind, and everyone near it is there because they can keep up. What this ward asks of you

• Thinking harder than anyone else in the room, then defending it.
• A high tolerance for being disliked while you are right.
• Interest in the puzzle that outlasts your interest in being comfortable.

From the Collider file

• Eight seasons built on Sherlock Holmes: House and Holmes, Wilson and Watson, and an apartment at 221B.
• Hugh Laurie taped his audition in a hotel bathroom in Namibia while shooting another film.
• By 2008 it was the most-watched television show on earth, with an audience around 82 million.

Chases the puzzle Difficult on purpose Usually right

SHH · Admitted Scrubs Sacred Heart Hospital, California This ward asks whether you can hold the tragedy and the absurdity at the same time.

You understand that medicine is devastating and ridiculous in roughly equal measure, and that the only sane response is to carry both at once. You are warm, self-aware and funnier than most people in your field. You use humor to get through terrible moments, which at Sacred Heart is a survival strategy rather than a flaw. You lean on the people around you and let them lean back, because here the laughter and the grief are inseparable. What this ward asks of you

• Humor that never curdles into cruelty.
• The honesty to admit you are still learning how to do this.
• People you can lean on, and the willingness to be leaned on.

From the Collider file

• Nine seasons from Bill Lawrence, filmed largely inside a real decommissioned hospital in North Hollywood.
• Working doctors have repeatedly named it the most accurate medical show on television.
• Zach Braff, Donald Faison and Sarah Chalke returned for an ABC revival that premiered in February 2026.

What Is 'Shrinking' About?

Premiering in 2023, Shrinking originally followed Jimmy (Segel), a therapist grieving the loss of his wife, who suddenly decides to throw out the book and start telling his patients what he really thinks, ethics and rules be damned. His guidance leads to dramatic changes in people's lives, most notably his own, beginning a three-season Emmy-nominated journey to come to terms with his loss, learn how to move on, and rebuild the relationships with the people closest to him. Season 4, Lawrence has previously teased, will be the beginning of a new chapter for the gang, though exact details for what it will be about are unclear. It'll take place after a time jump and, depending on reception, the streamer, and what the creators ultimately feel, may still have a couple seasons left to keep exploring this next arc.

Filming has wrapped on Shrinking Season 4, which is expected to premiere sometime in 2027. Stay tuned here at Collider for more on
