EXCLUSIVE: The DC Universe is no stranger to legacy casting.
The DCU's Chapter 1: "Gods and Monsters" is bringing fresh takes of various heroes and villains to life through film and TV shows in James Gunn's superhero reboot. However, as new stars are tackling some of the iconic characters, the franchise has also tapped various actors who have a long history with the DC brand.
During an exclusive interview with ScreenRant's Andy Behbakht for the 25th anniversary of Smallville, Michael Rosenbaum, who starred as Lex Luthor in the DC TV prequel, also had a voice cameo in 2025's Superman as one of the Raptor Guards, was asked if there is a possibility he could have a larger role in front of the camera in Gunn's DCU, and if there are other DC characters he would like to play. He began by stating, "I've done a lot of animated voices for a lot of characters in the DC world, but I haven't done much in the Marvel world. I did Guardians of the Galaxy, with a small role as Martinex in 2 and 3."
However, Rosenbaum stated that "I would love nothing more than to be a part of that. It's an incredible world. When I think about the character I would love to play, whether it's animated or live-action, I think about Riddler. Something where I could really be - not Lex Luthor, but somebody who can snap." The Smallville cast member also expressed how, "at the same time, I'd love to play a superhero. I'd love to play one of the good guys. I was the voice of the Flash in Justice League, and I loved it."
He also shared, "It's funny because you do a role like Lex Luthor, and you're thinking, "The offers are gonna come now that they know I can play this kind of character," but there's still that stigma. It's like, "But he was on a show, and now we're doing the movies," and the crossover isn't what we hoped it would be by now. But I would definitely love to delve into that. I'd love to play another villain, or to play a superhero."
Wally West is one of the many DC roles that he has voiced throughout his career, and while he was not one of the legacy castings to happen on The Flash TV show, Rosenbaum shared the following after being suggested during ScreenRant's interview that one way he could play the Scarlet Speedster in the DCU is if he time travels from the future to the DCU's present:
Michael Rosenbaum: I think they knew that I didn't want to come in as a guest star. They were very interested in me for Superman and Lois, and they were interested in me for some of the other shows, but I just wasn't interested. In my mind, I was Lex, and there can't be another Lex. In the multiverse, when Tom went back with Erica and they did that whole thing, they asked me to come back, and it just didn't feel right to me. I didn't know much about what they were going to do, and they wouldn't tell me.
So, I was like, "If I don't know, I'm not going to do it." In fact, I've never really been a guest star on a show. It's crazy. Maybe in the past, once, a long time ago. But it's not that I'm opposed to it. It's that the right role hasn't come along, where you know I connected to it and thought, "I could really add to this." I loved playing Lex. It was a dynamic, larger-than-life character, and I wanted to keep him grounded and real. He had emotions, and I wanted you to care about him, and I would like to bring that to another character. So, we'll see what happens.
With multiple upcoming DCU movies and TV shows in the works at DC Studios, there is plenty of time for Gunn and Rosenbaum to reunite once more, as DC Studios continues with building out their franchise. As the two of them are also good friends, it will be exciting to see if the Smallville star at some point gets to play a new character, especially if it's as a hero.
Smallville is available through home media release, while streaming on Hulu (via Disney+.)
