(CNN)If you miss seeing the Fresh Prince of Bel Air on screen, you're in luck.

Thanks to CGI de-aging technology, a younger, stealthier version of Will Smith -- who looks a lot like his goofy '90s sitcom character -- appears in the actor's upcoming movie, "Gemini Man."
In a trailer for the Ang Lee film released Wednesday, Smith plays an aging assassin who finds himself in the crosshairs of another killer who he just can't seem to shake.
After Smith's character Henry Brogen notices that an assassin tracking him knows his every move before he even makes it, it's revealed that Brogen's assassin is actually a younger version of himself.
