In “Looper,” Joseph Gordon-Levitt plays a hitman in the near future whose targets have been sent back in time; one day, the man who turns up turns out to be an older version of the assassin. To bring the premise to life, Gordon-Levitt had to look (and act) like Bruce Willis, who plays the older incarnation of his character, and that meant spending three hours a day in the makeup chair.

“That was really scary because you commit to that and there’s no real way out of it,” said “Looper” writer-director Rian Johnson of using practical prosthetics to make one actor look more like the other. “But the biggest thing is Joe’s performance, he’s really doing Bruce in a big and daring way, but he strikes a balance between obviously imitating Bruce and also building this organic performance.”

From a small piece on Looper in the Los Angeles Times.
