Zac Efron's five hottest moments in the new 'Neighbors' trailer
1. 0.55 A peek of pecs. 2. 1.20 THE GUN SHOW. 3. 1.36 What we're calling a kind of half-twerk thing. 4. 1.49 Tight white T-shirt and trackie bottoms. Hiyaaa! 5. 2.20 Full-on shirtlessness. You can watch the trailer below, but the film itself doesn't open in UK cinemas until May 9, 2014. Sadness. [youtube height="230" width="420"][/youtube]
