What Just Happened has premiered at the Sundance film festival and it threatens to ruffle a few feathers.Veteren producer Art Linson and director Barry Levinson have joined forces to create an insider's look at how the film industry works.And the film's not a send up, but rather a true depiction of how business gets done in the film making industry.De Niro plays a producer who at times is overloaded with the issues of prima donnas, crazy actors, shameless egotists and difficult marriages.But the back-biting in Hollywood might be too close to the truth for De Niro, after poor reviews for his choice of recent roles.© Independent Television News Limited 2008.
