Joseph Gordon-Levitt's 'SNL' Promos are Ninja-tastic (Video)
Joseph Gordon-Levitt has big plans for this weekend's Saturday Night Live.
He'll be singing. He'll be acting. He'll be dancing. He'll be ninja-ing. And he'll be traveling back in time to scoop dog poop.
All this in an hour and a half, with a few breaks for Mumford and Sons to play their lively brand of British folk rock. Or, at least so the Looper star promises in these new promos with Jason Sudeikis. But don't doubt him; he may just be the next Batman, after all.
