Director Ang Lee shot Gemini Man in 4k digital 3D at 120 frames per second instead of the standard 24. What you get is a sharp image that looks like that "soap opera effect" or "motion smoothing" setting on your television. It looks weird, however it does add some ultra realistic pop to the action scenes.
It's the very near future and assassin Henry Brogan (Will Smith) has completed his final job. His plans of retiring are interrupted by a clone of his younger self sent to kill him. Along with DIA agent ally Danny Zakarweski (Mary Elizabeth Winstead), Henry goes on a globetrotting journey to find out why he has been targeted for death.
The younger Will Smith was created through motion-capture CGI and mostly looks pretty damn convincing, except for a daylight scene late in the film. The performances from Smith and Winstead are good, but they didn't have that much to work with.
What brings the movie down, though, is the moldy spy/espionage plot and a stale 20 years "in development" screenplay that underlines every predictable plot point as if it is some amazing revelation. Plus, the dime-store introspection about cloning just brings everything to a standstill. Even Lee's direction is sluggish, which is surprising from the director of stunning films like Crouching Tiger, Hidden Dragon and Life of Pi.
