The only person who can beat Will Smith is ... himself?

A new trailer for "Gemini Man" reveals more of Ang Lee's sci-fi thriller, which has Smith playing dual roles: an aging assassin hunting down his younger clone. The movie uses CGI to make the 50-year-old Smith look just like he did when he was 23.

In the action-packed trailer, Smith confronts his younger self, who has been bred to be a killer by Clive Owen. And now this young assassin, dubbed Junior, is coming after the older, more experienced version. They're soon battling it out, throwing punches, grenades, and even motorcycles at each other. Their cat-and-mouse game is complicated by the fact that they can predict each other's moves.



Unlike how they de-aged Samuel L. Jackson in "Captain Marvel," a recent behind-the-scenes featurette revealed that the effects used in "Gemini Man" are different.

“This is not de-aging. This is not face-replacement," VFX supervisor Bill Westenhofer explained. "What you see for Junior is a completely digital creation, 100 percent driven by Will Smith’s performance capture."

"This technology is going to change how movies are made," Smith said.

"Gemini Man" also stars Mary Elizabeth Winstead and Benedict Wong, and opens in theaters October 11.
