The story of ''GEMINI'' is a futuristic thriller about an aging government assassin named Alexander Kane who is pitted against Rye, a rival half his age. Rye, it turns out, is a clone of Alex, a living reminder of his vicious heyday. The idea was to cast an older male lead as Kane and then digitally de-age him, a technique Hollywood wouldn't attempt until X-Men: The Last Stand and then use more extensively in The Curious Case of Benjamin Button and TRON: Legacy.
Rye could anticipate and counteract Alex's every maneuver, thus making him the perfect adversary. Alex, a loyal super-soldier for the Orwellian "Administration" and their nefarious Intelligence Office, is put on the defensive because of Rye's relentless manhunt. Alex must find out why Rye was created and why his patrons have turned on him. On the run from those who would destroy him, Alex lays low in the home of a woman and her young son. Needless to say, Alex develops feelings for them.
Well the film was in development for almost a decade[It was in pre-production since 2000] and it defeinetely had lots of interesting choices for the lead role. Stars such as Harrison Ford, Sean Connery, Nicolas Cage, Mel Gibson, and Jon Voight were all rumored for the lead role(s) at different points. One special effects house even created CGI test footage combining imagery from Gibson's Payback with shots of a younger Mel in The Year of Living Dangerously. The project was back in the news as recently as 2009 when L.A. Confidential's Curtis Hanson was reportedly attached to direct.
On YOUTUBE Joe Carnahan[Director of movies such as THE GREY THE A-TEAM NARC] was at one point up to direct the film and he prepared a test reel with Clint Eastwood as the main character. ENJOY!!!
