The trailer of Ang Lee's Gemini Man was released on April 23, the film stars Will Smith as an elite assassin. Will Smith says the emotional and physical challenges of making Ang Lees 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 a 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.
