Apparently, Warner Bros. has not cleared it out with Motion Picture Association of America when it attached the R-Rated comedy's trailer to 'Source Code'.
For not clearing it out first with MPAA, "The Hangover 2" trailer has been pulled from theaters. Preview of the R-rated film starring Bradley Cooper appeared in front of "Source Code" this past weekend but the two films' rating don't quite add up because the latter is PG-13.
In a statement to THR, Warner Bros. said, "In our haste to meet the placement schedule for this trailer, we failed to properly vet the final version with the MPAA. We acted immediately to correct the mistake and removed the trailer from screens."
The full official trailer includes a scene with a monkey biting a pretend wiener and humping on a water bottle. EW's sources said nobody has filed a complaint against the trailer when it was played over the weekend but Warner Bros. reportedly would be making changes to the footage and show it on theaters again on April 15 in front of "Scream 4" which is also R-Rated.
"The Hangover 2" is scheduled for release in the United States on the May 26 during Memorial Day weekend. The gang from the first film are in Bangkok to celebrate Stu's wedding when they discover themselves in another state of black-out.
