Adrien Grenier of Entourage is currently filming a documentary called Teenage Paparazzi, for which he has enlisted Alec Baldwin, Whoopi Goldberg, Eva Longoria, Rosie O’Donnell and others.

Grenier’s film, which surfaced on gossip sites when the actor was seen around Los Angeles with interview subject Paris Hilton, explores his relationship with a 14-year-old paparazzo who took his photo. The docu will feature Grenier interviewing actors and commentators — including Martin Landau, Noam Chomsky and "Daily Show" comedian Lewis Black — about the culture of fame.

[Producer Matthew] Cooke, who is functioning as a "sounding board" for the director, said "Paparazzi" will interweave the relationship portrait with philosophical interviews in the style of Richard Linklater’s "Waking Life [clip after the jump so you understand what we're dealing with]." It is being shopped to distributors and might be unveiled as a feature or miniseries. [THR]

Ooh, I can’t wait.  I’ve always wanted to see a movie that recreates the experience of catching your junior-high-droput pot dealer in a moment of introspection.  Fascinating thought, Entourage guy! Tell me about quantum mechanics!"

Dakota Fanning and her sister Elle are being replaced by Abigail Breslin (Little Miss Sunshine) and Sofia Vassilieva in the Nick Cassavetes drama My Sister’s Keeper.

Sources said Dakota Fanning balked at a request that she shave her head for the role and both sisters withdrew abruptly.

Reached for comment, Fanning said, “Only dykes and hippies shave their heads,” in between packs of unfiltered Camels.  “Don’t tell nobody I said that.  I ain’t afraid to kill a snitch."

Breslin, who was Oscar-nominated for "Little Miss Sunshine," will take over the role of a young girl who sues for emancipation from parents who conceived her as a genetic match so she could prolong the life of her ailing older sister. Cameron Diaz plays the mother of the girls, a tough lawyer who takes her own case in court. Alec Baldwin plays the attorney who represents the child.

Something something “Rude little pig,” *rimshot*
