“[Rooney Mara] was sent over to me to start teaching her to ride,” says Kell. “She had never been on a bike before, so we had to start easy. I’ve trained many actors to ride over the years, and I must say that Rooney was one of the best. She was fearless, but smart. In three days, we had her doing everything that she needed to do on camera at 35 mph.” (via Of motorcycles and movies)
