Seth Rogen and meat-glazed thirst trap Zac Efron have an idea for a movie: There’s a zombie, tied to a chair, and Rogen is going to kill its brains with a huge sword he stole from a Renaissance Faire, but Efron, whose muscles are barely contained by a standard T-shirt, notices that the zombie is one of his frat bros and tells Rogen they can’t kill the zombie. “When you’re brothers, it’s forever!” The movie is called Neighbors 3: Zombies Rising. Good idea, right? Mmm. Baywatch bae Efron isn’t the only one who has sand in his mouth, ’cause suddenly we’re really #thirsty.
