And a lot was revealed about Shannen Doherty, who was the reputed bad girl of the show. According to the film, Doherty displayed a lot of bad behavior that her co-stars had difficulty dealing with. Doherty often got herself into fights, some with her co-stars and some with other people. She has been arrested and was always late for filming. At first, Tori Spelling defended her tardiness because she was her friend, but Doherty made her biggest mistake when she dared to threaten Spelling. Doherty allegedly warned Spelling to “watch her back” after arriving late on set again. After that incident, Doherty was never seen again in the series. Also, Shannen Doherty and Jennie Garth were shown having a fight in a carpark because of a red dress they both wanted to wear. In the next scene, Doherty was arrested for picking a fight in the club.

The police officer even said to her, “Do I know who you are? Yes. You are a big pain in the ass. Everybody thinks that.”

Ian Ziering also tried to talk some sense into her, “You’re like a shark, you’re like a tornado – you’re like a mixture between a shark and a tornado.”

At the end of the scene, Doherty crashes Ziering’s sports car and Ziering predicts the creation of Sharknado the movie.

While Shannen Doherty is known for her antagonistic personality, all that aggression cannot seem to subdue her present condition.

Doherty recently revealed that she was diagnosed with breast cancer and might undergo chemotherapy and mastectomy.

Unfortunately, she was let go by her management firm Tanner Mainstain. The firm was allegedly responsible for her medical expenses but failed to pay them, and did not inform the ‘90210’ star.

Doherty has filed a suit against Tanner Mainstain, claiming that her cancer could have been prevented if the firm had just done its job for her.
