Jennifer Aniston refused Courtney Cox's proposal to do a documentary about "Friends" star, arguing she wants to distance from her character Rachel Green.

All the "Friends" actors had already agreed to do the documentary based on the show, except for Aniston.

According to Moviehole.net, a source said: "All the cast members are up for a documentary based on the show, which would have featured exclusive interviews with the cast, except Jennifer Aniston.

Rumor is she is still too distraught about the split from Brad Pitt, while others cite the fact that she wants to move away from her Rachel image for good."
