LONDON — Nicole Kidman is in talks with Lars von Trier to appear in “Wasington,” the final part of the Danish auteur’s controversial American trilogy.

Kidman starred as gangster daughter Grace in the first movie, “Dogville,” but was unavailable for the second installment, “Manderlay.”

Bryce Dallas Howard took the role of Grace in “Manderlay,” which had its world premiere at Cannes last week. Kidman told the U.K.’s Daily Mail she and Howard will “share the role” in the third movie.

“Lars has been talking to Nicole as well as Bryce, the idea being that they would both be in ‘Wasington,’ ” confirmed Vibeke Windelov, von Trier’s producer.

Production has been delayed until 2007 because von Trier wants more time to work on the script. In the meantime, he will shoot “The Managing Director of It All” early next year.
