It haa been confirmed that the acapella group Pentatonix will appear in "Pitch Perfect 2."

The "Pitch Perfect 2" trailer was released November 20. Many fans and moviegoers said that this trailer teases another hilarious flick to watch for. However, since Pentatonix has been confirmed to join the comedy flick, why wasn't that the acapella group shown in the trailer?

Based on the exclusive interview of Fanlala with the acapella stars, the group talked about their album which was released in October. In the same interview, Mitch Grassi said that he didn't want to give much information (or much spoilers about the comedy movie). But he said moviegoers should expect that they are the competitor of the protagonist acapella group and they only have a cameo appearance.

The trailer of "Pitch Perfect 2" shows the new challenge of the acapella group led by Beca (Anna Kendrick) with Lilly Okanakamura (Hana Mae Lee) and Fat Amy (Rebel Wilson).

The next challenge of the group is to win World Championship of A Capella. Elizabeth Banks said on the trailer, “where every four years the best from around the globe compete for world domination."

The problem of this group according to Banks, “No American team has ever won.”

"Pitch Perfect 2" will hit U.S. theaters on May 15, 2015
