Nicholas Stoller’s Bad Neighbours 2 reunites Seth Rogen, Rose Byrne, and Zac Efron in a suburban war against a newly formed sorority next door. As Mac and Kelly try to sell their house, their plans fall apart when a rowdy all-female party house moves in. The film mixes outrageous college comedy, suburban chaos, and gender-flipped rivalry with returning and new characters.
