Brad Pitt is in talks to star in Terrence Malick's new drama "Tree of Life" reports Variety.

Pitt would replace Heath Ledger who was scheduled to star with Sean Penn in the Malick penned and directed drama.

Though Penn is booked to play the title character in the Gus Van Sant-directed Harvey Milk, he's still expected to play a supporting role in Tree of Life.

Production is scheduled to begin in the spring.
