A new trailer for the Hangover Part II film was pulled from movie theaters.

The scene in which a monkey was sucking on a bottle placed under an old man's sarong was allegedly the scene that got the trailer pulled, though it has not been confirmed with Warner Bros.

According to the Los Angeles Times, the ad was not properly vetted by the Motion Picture Association of America, which ensures movie trailers follow the ratings system. The group asked the distributor, Warner Bros., to make sure they are in sync.

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 remove the trailer from screens, Warner Bros., said in a statement.

The trailer premiered in front of Source Code last Friday. The revised version will appear in movie theaters on April 15 in front of Scream 4. The film opens in theaters on May 26.
