Biel Was Unhappy With Her Role
Not many people know this, but it seems that Jessica Biel was unhappy with her character and her role in the show. There was a lot of tension generated on set, as Biel had grown dissatisfied with her character, Mary Camden, by the fourth and fifth seasons of the program. It seems the actress was unhappy with the direction the writers were going, developing her character.
Biel went to extremes to show her displeasure, and at one point actually tried to get herself fired so she could get out of her contract. She made a decision to do a racy photo shoot for Gear Magazine in an attempt to get axed. She later regretted her decision and remained with the show until the sixth season.
