The film stars Will Smith as Henry, a highly trained expert-level hitman who's getting up there in age. Despite all his skills, nothing seems to matter when it comes to facing off against his latest opponent, who seems to know all his moves before he makes them. How? Because he is him (albeit a clone of his much younger self, thanks to a scientist played by Clive Owen).
In addition to heavy-hitters like Smith and Owen, the film stars Mary Elizabeth Winstead, Benedict Wong, and Douglas Hodge. Watch the trailer for Gemini Man above before it hits cinemas on Oct. 11.
