Rainman director Barry Levinson will direct the David Mamet-written Assassination, says Deadline.
Mamet had been originally set to direct the film, which tells the story of how infamous Chicago mobster Sam Giancana arranged the assassination of President John F. Kennedy as payback for trying to bring down organized crime after the mob helped put JFK in the White House.
Al Pacino and Shia LaBeouf remain attached to the film.
