Robert De Niro plays a movie producer just trying to make it through the day in the Tinseltown comedy 'What Just Happened,' and ET is with the Oscar winner and co-stars Robin Wright Penn and Sean Penn for their big New York premiere at the Museum of Modern Art!

In theaters October 17, 'What Just Happened' is based Hollywood producer Art Linson's bestselling memoir, chronicling a middle-aged producer caught between his estranged wife, clever kids, childish directors, stubborn actors and the unflinching studio executives who will settle for nothing less than mediocrity in order to get a movie made.

Written by Linson and directed by Barry Levinson (who previously paired with De Niro for the political comedy 'Wag the Dog'), the film also stars Catherine Keener, Stanley Tucci, John Turturro, Bruce Willis and Kristen Stewart.
