Ang Lee has cast his son Mason to play martial arts legend Bruce Lee in a new biopic.
The 68-year-old filmmaker, whose previous credits include Crouching Tiger, Hidden Dragon and Brokeback Mountain, is said to have been working on the project in secret for a while.
Dan Futterman is currently working on a script that has seen previous drafts by Jean Castelli, Alex Law, Mabel Cheung and Wells Tower.
Mason, 32, has also been training for the last three years in Asia in preparation for the role. He has previously starred in The Hangover Part II and Dead Pigs.
Bruce found global success in a series of successful Hong Kong films. He is regarded as one of the most influential martial artists of all time but tragically died aged just 32 in 1973.
Ang told Deadline: "Accepted as neither fully American nor fully Chinese, Bruce Lee was a bridge between East and West who introduced Chinese Kung Fu to the world, a scientist of combat and an iconic performing artist who revolutionised both the martial arts and action cinema.

"I feel compelled to tell the story of this brilliant, unique human being who yearned for belonging, possessed tremendous power in a 135-pound frame, and who, through tireless hard work, made impossible dreams into reality."
Elizabeth Gabler and Marisa Paiva are overseeing the film for Sony's 3000 Pictures with Lawrence Grey, Shannon Lee, Ang Lee, Ben Everard and Brian Bell producing.
Elizabeth said: "Bruce Lee is a longtime passion project for Ang and a deeply emotional story depicting the triumphs and conflicts of one of the foremost real-life action heroes of our time.
"All of us at Sony and 3000 Pictures are proud to help Ang and his filmmaking team create what we believe will be an extraordinary theatrical event."
