New 'Neighbors' trailer: Zac Efron gets fratty, Seth Rogen gets mad

It’s fraternity versus family for Zac Efron and Seth Rogen in the new trailer for their upcoming comedy Neighbors.

Following the release of a red-band trailer last month, the latest preview shows a young couple (Rogen and Rose Byrne) trying to remain hip and cool after the birth of their first baby when a frat, led by Efron, moves in next door. A newborn baby and beer pong: What could possibly go wrong?

Looking at the trailer below, plenty. Beware of fireworks and flying balls when the film is released May 9, 2014.
