Chabon adaptation will be directed by 'Dodgeball' vet

Sienna Miller and Peter Sarsgaard may take leading roles in a feature adaptation of Michael Chabon's 1988 novel "The Mysteries of Pittsburgh."

According to The Hollywood Reporter, Miller is in final negotiations and Sarsgaard is in talks to join the film, which will now apparently be directed by Rawson Marshall Thurber ("Dodgeball: A True Underdog Story"), based on his own script.

Chabon's debut novel focused on one wild and sexually adventurous summer in the life of a recent college graduate named Art Bechstein. The lead role has yet to be cast, but Miller and Sarsgaard would play Jane and Cleveland, two of Art's paramours.

Michael London will produce the project, which will reportedly begin shooting in Pennsylvania sometime this fall.

Miller, Jude Law's on-again/off-again/on-again/off-again/on-again/off-again love, most recently appeared in the winter dud "Casanova" and will play Edie Sedgwick in the fall release "Factory Girl."

Sarsgaard's busy 2005 included "Flight Plan," "Skeleton Key," "The Dying Gaul" and "Jarhead."
