Sienna Miller is in final negotiations and Peter Sarsgaard is in talks to star in "The Mysteries of Pittsburgh," based on Michael Chabon's 1988 debut novel says The Hollywood Reporter.

The story, which marked Chabon's ("Wonder Boys") literary launch, chronicles the last summer of Art Bechstein's youth and revolves around his eccentric circle of friends including Jane (Miller) and Cleveland (Sarsgaard).

Rawson Marshall Thurber ("Dodgeball: A True Underdog Story") is on board to direct based on a screenplay he adapted from Chabon's coming-of-age book.
