Peep EXCLUSIVE (And NSFW) Trailer For Zac Efron's 'Neighbors'

If you're wondering what the big deal is with our exclusive redband trailer for next year's comedy, "Neighbors," we've got two words for you: Zac Efron. And two more: Dave Franco. And also, two more: TIGHT SHIRTS. (When they're wearing them, that is—and on at least one memorable occasion in this preview, Zac...well, isn't.) Ready to watch? YEAH YOU ARE.

Featuring Zac and Dave as a pair of powerful mischief-making bros with pretty faces and phenomenal eyebrows, and Seth Rogen and Rose Byrne as a young married-with-kid couple living next door to the frat house where they take up residence, "Neighbors" looks to be a sort of "Animal House" meets "Old School" meets "Knocked Up" combination—the kind of movie that makes you laugh, then wince, then laugh harder—with the bonus draw of more on-screen togetherness for Seth and Christopher Mintz-Plasse, who also makes an appearance. (We love their bro chemistry, and we're not ashamed to say so.) The movie is out in theaters May 2014.

What do you think of the first look at "Neighbors"?
