The ending of The Thing grows more mysterious after John Carpenter shuts down all existing theories.

1982's The Thing ends with R.J. MacReady (Kurt Russell) and Childs (Keith David) as the only remaining survivors of the research team stationed in Antarctica, and both suspicious that the other may be infected by the eponymous shape-shifting alien. The movie concludes with MacReady saying, "Why don't we just wait here for a little while, see what happens?" It is an ambiguous ending and has led to decades of various theories about the fates of Russell and David's characters, along with that of the alien itself.

At the Academy Museum gala, The Thing director John Carpenter was asked about the worst theory he has ever heard regarding the ending. Rather than share what he believes to be the worst one, the filmmaker explains that "every idea that people have is not the right one. And I know the right one. It's right in the movie too. There is a big clue. No one has guessed it." Check out his full response below:

Carpenter's assertion that none of the theories are correct after 44 years will further fuel the debate, as will his insistence that the answer can be found via a significant clue in the film. Meanwhile, other media have further complicated the enduring questions about the movie's ending.

The Thing's cliffhanger was answered over 30 years ago by the comic series The Thing from Another World, where MacReady and Childs are found by Argentinian soldiers, who take the men back to their base, and determine after testing that neither of them are infected. However, later in the series, Childs does get infected by the alien and hunts MacReady.

In addition to the comics from the 1990s, there is the 2002 video game The Thing, and in this sequel story, neither MacReady nor Childs got infected. The game's events are treated as canon by many. However, per Carpenter's latest comments, if all theories about the ending are wrong, which would presumably include those leading to the stories of the comics and the video game, neither one may be considered canon after all.

While the debate about the ending rages on, Carpenter's stance on the ending remaining unsolved provides a compelling reason to re-watch the film, just as interviewer Reece Feldman says he will after the director's response. With this ambiguity being part of the movie's legacy and providing infinite re-watch value, there isn't much incentive for the filmmaker to ever explicitly confirm the "right" idea about the film's conclusion.

There has also been an argument that the fates of MacReady, Childs, and the alien ultimately do not matter, as the movie's thematic exploration of paranoia and trust remain the same regardless of the answers. This is similar to how Russell interprets the ending of The Thing, telling MovieWeb earlier this year that "Then when you finally get to the end, you have these two guys that both have a legitimate reason to suspect the other, and it's just, in other words, it's a movie about paranoia, and it isn't going away. It's not going away."

The Thing is based on John W. Campbell Jr.'s 1938 novella Who Goes There? and is a remake of the 1951 movie The Thing from Another World. Along with Carpenter directing, Bill Lancaster wrote the screenplay, and Russell and David were joined by Wilford Brimley as Blair, T.K. Carter as Nauls, David Clennon as Palmer, Richard Dysart as Dr. Copper, Charles Hallahan as Norris, Peter Maloney as George Bennings, Richard Masur as Clark, Joel Polis as Fuchs, Thomas Waits as Windows, and Donald Moffat as Garry.
