1. Neighbors 2: Sorority Rising
Box office: $55.3
Not nearly as successful as the 2014 original, Neighbors 2 flips the script. This time Mac (Seth Rogen) and Kelly (Rose Byrne) – the young couple who are trying to raise their kids (with another one coming) in relative peace – have to contend with a loud sorority next door. They decide to take on Kappu Nu with the help of Teddy (Zac Efron) from Neighbors. This girl-power sequel features Chloe Grace Moretz. Kiersey Clemons and Beanie Feldstein, and a cameo from Selena Gomez. The stoniest scene is when Mac rips off a large bag of Kappa Nu's weed at an outdoor concert and gets chased until the bag opens and the contents spill out everywhere.
