In the funny new mockumentary Theater Camp, a summer camp for musical theater kids falls on hard times when its founder slips into a coma. The movie stars Ben Platt and Molly Gordon as two codependent instructors staging an original musical, and Jimmy Tatro as the business influencer son of the camp’s founder, who reluctantly takes over the camp. Directed by Gordon and Nick Lieberman, the film both skewers and glorifies the love of theater.
