Fresh Prince After Dark - S4-E9
Visible crew/equipment: In the episode where Hilary poses for Playboy, Hilary's strap-on mic is visible on the back of her red dress when she, Will, and Carlton first enter the Playboy party. It is gone in subsequent scenes.
Answer: Yes. It's very true. Janet quit at the end of the third season because she claims that Will acted horribly, bullied cast and crew on the set and got her fired for no reason. Alfonso Ribeiro however has called her "cuckoo" and stated that her claims were baseless. He also stated that she was very difficult to work with on set. Even James Avery agreed and often had to remind her that the show was called "The Fresh Prince of Bel-Air" and not "Philip and Vivian of Bel-Air."
