Most people would be thrilled if Zac Efron, Dave Franco, Christopher Mintz-Plasse, and Jerrod Carmichael moved in next door… at least most ladies would! But in the new movie “Neighbors,” it proves to be a complete nightmare for Seth Rogen and Rose Byrne. They play a young couple with an adorable baby who get into a turf war when a frat house of 50 guys moves in next door. Fusion’s Jessica Blank sits down with the cast and gets the fratty details on the R-rated, hilarious new movie. She even asks them to participate in a pretty strange pledge ritual: the elephant walk.
