Sean Penn, Bruce Willis, Stanley Tucci, John Turturro and Kristen Stewart have joined Robert De Niro in What Just Happened?, the Barry Levinson-directed comedy, according to Variety.
Shooting begins March 22. De Niro and his Tribeca Productions partner Jane Rosenthal will produce with Art Linson.
Linson, the veteran Hollywood producer, wrote a screenplay that was inspired by his memoir. In the fictional film, De Niro plays a desperate movie producer trying to preserve some dignity as his soul is slowly destroyed by the machinations of Hollywood and the breakup of his second marriage.
