Edgy and incisive Tinseltown satire features a stellar performance by Robert De Niro as a cagey veteran producer navigating the treacherous shark-filled waters of Hollywood and trying to keep his professional and personal heads above water. Bruce Willis and Sean Penn appear as themselves. Directed by Barry Levinson and written by Art Linson, who based the screenplay on his 2002 book "What Just Happened: Bitter Hollywood Tales From the Front Line."
