While James L. Brooks' new film doesn't quite have a title yet, the cast is rounding out with the possible addition of a screen legend. According to Variety, Jack Nicholson is in negotiations to join the cast of the Untitled James L. Brooks Project.

If Nicholson should sign on, he would join a cast that already includes Paul Rudd, Reese Witherspoon and Owen Wilson. It was said that Bill Murray was in extensive talks to portray the father of Rudd's character, it seems that Murray has lost interest in the film and Nicholson may come on board as the last key member of the cast.

The story is said to revolve around a love triangle, with both Rudd's character, a white-collar executive, and Wilson's character, a pro baseball pitcher, both trying to win Witherspoon's character over.

Nicholson is no stranger to Brooks' work, with two of his three Oscar awards coming from the Brooks films Terms of Endearment and As Good As It Gets.

How Do You Know was released December 17th, 2010 and stars Reese Witherspoon, Paul Rudd, Owen Wilson, Jack Nicholson, Kathryn Hahn, Mark Linn-Baker, Lenny Venito, Molly Price. The film is directed by James L. Brooks.
