Here’s the trailer for the third and final Hangover movie, which hits theaters May 24th. Up until now the plot has been kept under wraps, but the trailer reveals that it’s about Ed Helms and Bradley Cooper’s characters taking Zach Galifianakis’s character to a mental health center after the loss of his father, only to be stopped by a criminal (John Goodman) who’s looking for Leslie Chow (Ken Jeong). Oh, and Melissa McCarthy has a cameo, which is probably like 30 seconds longer than her bit in the trailer.
