Adrian Grenier has assembled and all-star cast to appear in his upcoming documentary Teenage Paparazzi. The latest to sign on are Alec Baldwin, Whoopi Goldberg, Eva Longoria and Rosie O'Donnell.

Grenier's film explores his relationship with a 14-year-old paparazzo who took his photo. Grenier will interview other actors and commentators — including Martin Landau, Noam Chomsky and "Daily Show" comedian Lewis Black — about the culture of fame. Producers say it might eventually end up being shopped as a miniseries.
