“I start the movie off. The first thing you see in the movie, which is pretty cool. I do this whole, like, parkour sequence,” Justin WWD. “I’ve never really done something like that before. I didn’t expect Ben [Stiller] to be so hands on…It was really cool to have him direct me in such a nonthreatening way. I wasn’t intimated at all.”
