Although the firing on Celebrity Apprentice was for entertainment, the firing Gary Busey suffered this week was much more real. TMZ says Gary Busey was fired from the movie he was filming because a woman claimed Gary made inappropriate comments to her. I am sure he did. I am also sure that just about everything that comes out of Gary's mouth is inappropriate to some extent. Apparently the other cast and crew also complained about him so the production team fired him and hired someone else to re-shoot all of the scenes Gary had completed. He had already finished half of his shots so he must have really been out of control.
I think that Gary Busey tries to be Gary Busey. People expect him to be a little off so now he exaggerates that off-ness and instead of being quirky or cute, it becomes annoying.
