In 2010, Christopher Nolan's "Inception" arrived, and even the people who hadn't been paying attention finally found out that Joseph Gordon-Levitt wasn't little Tommy Solomon any more. His character in the peculiar dream-heist movie, Arthur the point man, is arguably the single coolest character in the film, which is saying something when the rest of the cast includes people like Leonardo DiCaprio, Tom Hardy, Elliot Page and Cillian Murphy. 

A lot of this has to do with Gordon-Levitt's iconic hallway scene. It ranks among the most epic movie fights out there, made all the more impressive because the physics-defying battle in the spinning hallway was a practical effect that took three weeks to shoot, and required Gordon-Levitt to prepare with two weeks of arduous stunt training. 

"It was just about the most fun I've ever had on a movie set," the actor described the experience in an interview with Collider. " It was also, probably, the most pain I've ever been in on a movie set, physically, but you know, pain in a good way, like in the way I guess athletes must get when they have to put on their pads and they tape up their ankles and they get a little beat up throughout the day, but that's just part of slamming yourself into walls and jumping around all day."
