Star Colin Farrell couldn't be there, so it was young Hollywood's leading men who stole the show at Wednesday night's Fright Night premiere!

The event, at the Arclight in Hollywood, brought out Dave Franco (that's right -- James' little bro!), Christopher Mintz-Plasse (aka McLovin from Superbad) and Anton Yelchin.

We couldn't take our eyes off of Dave! The hottie, 26, is on the verge of a major career! He's been acting since 2006, mostly on TV shows like Scrubs, but now Dave is transitioning into movies. He stars in Fright Night, and up next he's in 21 Jump Street with Channing Tatum in Jonah Hill.

Now the question is ... is he as weird as James?
