During a conversation with Entertainment Weekly, James Watkins and Tom Rhys Harries talked about the now-infamous airplane bathroom sequence featured in the trailer. Even after directing the sequence, Watkins admitted it still made people squirm. As he reenacted crew members turning away and covering their faces, he explained why the moment hits such a nerve. Clayface marks the first R-rated body horror movie in DC’s cinematic universe. And if one scene was enough to make crew members look away during production, audiences should probably prepare themselves before stepping into the theater.
