Cinematographer Emmanuel Lubezki revealed in an interview with Les Cahiers du Cinéma that Malick is hoping to release a six-hour cut of The Tree of Life that likely features more of central character Jack's (Sean Penn) childhood.
"Terry is working on a six hour-long version of the movie," Lubezki said. "What I've seen [of this] is absolutely incredible, it's wonderful. The longer version will likely, for the most part, relate to the children part."
The cinematographer went on to reveal that the initial cut of the film was around eight hours long.
"We maybe have... shot 600,000 metres of film," said Lubezki.
Tree of Life star Jessica Chastain recently said that the film needs multiple viewings in order to be understood, claiming that one constantly discovers new elements upon each viewing.
The Tree of Life earned the prestigious Palme d'Or at the Cannes Film Festival in May.
