Los Angeles: Actor Will Smith says the emotional and physical challenges of making Ang Lee's science-fiction thriller "Gemini Man" have been the most demanding of his career.
"The emotional and physical challenges of making this film have been the most demanding of my career. Lee is pushing the limits to give people an experience in the movie theatre that you can't get anywhere else," Smith said in a statement.
"This is not only an action film, but an exploration of what one's younger self can ultimately teach one's older self. I'm 50 years old now, and the irony of becoming 23-year-old junior in this film is that 23-year-old me wouldn't have been ready for this experience or to take on this role.
"Our hope is that this story provides something for everyone -- never before seen cinematic wizardry, nuanced, relatable characters and next-level action," he added.
"Gemini Man" is touted as an innovative action-thriller starring Smith as Henry Brogan, an elite assassin, who is suddenly targeted and pursued by a mysterious young operative who seemingly can predict his every move.
The film will release worldwide on October 11. The Paramount Pictures movie will be exclusively distributed in India by Viacom18 Motion Pictures.
Lee feels lucky to be "able to experiment and test the limits" of new digital cinema.
The Oscar-winning director said: "This story is not one that could have been told with cinema as we know it. However, thanks to incredible new digital technology, not only can we finally see both younger and older Will Smith embodied together on screen, but we can also experience the story in a deeply immersive way.
"It is my great fortune to be able to experiment and test the limits of what new digital cinema has to offer us. No less so to be able to work with two Will Smiths - One beautifully sophisticated, the other exuberantly honest. In my opinion, this is Will at his very best, and when the two come together, it is something truly magical."
