MPAA Pulls 'The Hangover: Part II' Trailer From Movie Theaters?

This week, movie theaters across the country received a notice asking them to remove the movie trailer for The Hangover Part II from Source Code and to delete the digital trailer files from their servers. /Film reader Chris sent us a photograph of the notice, which was sent out by Warner Bros Pictures but specifically mentions the MPAA. No reason for the removal is listed on the notice. We contacted Warner Bros for clarification and they responded with "No Comment".
