The comedian, who's dad died in the attack, called out Sheen in a since-deleted Instagram post Monday night.
"Spoiler alert: I know how it ends..I would respect this movie more if it had Vin Diesel driving a Lambo out of Tower 2 at the last second. F-ck this movie. NOT ONLY THAT BUT YOUR STAR OF THE MOVIE CHARLIE SHEEN IS A 9/11 CONSPIRACY THEORIST. YOU F-CK," he wrote.
The film appears to focus on five people, including Sheen, who are trapped in an elevator in the World Trade Center's North Tower on 9/11 and must work together to escape. Whoopi Goldberg also stars in the film, which doesn't look like it will be receiving any Oscar nominations, as a security guard who assists in getting the group out of the elevator -- if they don't plummet to their deaths first.
Davidson joined many others slamming the trailer on Twitter for various reasons beyond a 9/11 conspiracy theorist's involvement.
