10 TV Shows That Were Disrupted By Behind-The-Scenes Feuds

6. Alleged Racial Slurs And Diva Behaviour Curtails Grey's Anatomy

The drama that took place behind the scenes of Grey's Anatomy was probably one of the most well-publicized cast meltdowns in television history. So much so that it completely overshadowed the actual drama on the primetime soap opera. The story goes that Isaiah Washington and Patrick Dempsey almost came to blows on the set and during the heat of the moment, Washington used a homophobic slur.

It was widely reported that Washington had used the derogatory term against fellow cast member T.R. Knight, who came out as gay shortly thereafter, and Washington's career took a swan dive. He gave a forced apology to the LGBT community, but the damage had been done. In June 2007, ABC announced that they would not be renewing his contract, and one of the show's most popular characters left after the third season.

This is, of course, to say nothing of the repeated rumors of backstage diva behavior from Katherine Heigl, who had made it clear that she wanted off the show after her film career showed signs of taking off. She certainly wasn't shy about criticizing the show, publicly stating that she didn't submit her name for Emmy consideration in 2008 because she didn't think the material she had been given was worthy of it.

Needless to say, this created a little bit of tension between her and the cast and crew.
