Kel Mitchell had a lot of fans back when he starred as a regular on Nickelodeon’s “All That” and “Kenan and Kel.” It seemed like his decline began when he lost out to his former costar Kenan Thompson for a spot on “SNL” in 2003.
Now that Kenan has become the show’s longest-standing cast member, the two have virtually stopped speaking, besides an appearance together on “The Tonight Show.” Nowadays, Mitchell appears in kids’ shows and smaller roles.
Phoebe Cates
Phoebe Cates made jaws drop... for both men and women alike. She starred in 1982's "Fast Times at Ridgemont High." She continued to appear in several movies throughout the '80s and early '90s. However, following a time period during which she was completely absorbed in her film career, she disappeared.
It seemed that she retired from her career as an actress in 1994 to focus on her marriage to Kevin Kline and their two children. Since her retirement, she has acted in only one movie, "The Anniversary Party," as a favor to Jennifer Jason Leigh, who was the film's director.
Kelly McGillis
McGillis became a major star after appearing in Top Gun. However, her negative experience in the 1989 "Cat Chaser" discouraged her from wanting to pursue her acting career any further.
She continued to star in some films and TV shows here and there until she settled on being a theatrical actor and character TV actress. She has since come out as a lesbian in 2009.
Freddie Prinze, Jr.
Freddie Prince Junior was the teen heartthrob of the 90s after starring in the "I Know What You Did Last Summer" series. Since his guest role on 24, the actor has been doing voice acting for animated shows and video games. According to Prinze, his experiences with Kiefer Sutherland on the set of 24 caused him to want to quit acting because they were so negative.
While Freddie is not acting so much these days, he is getting to enjoy more quality time with wife, Sarah Michelle Gellar, and their two children.
Mischa Barton
Mischa's claim to fame was in 2003 when she played Marissa Cooper in The O.C. She played this part for three years. During this time, Mischa was at the peak of her career. Capitalizing on the show's fame, the star attended parties all over the world. She was once named Entertainment Weekly’s “It Girl” during the first year of the show and quickly became a paparazzi favorite.
Mischa explains her demise as a result of “living a jet-set lifestyle. If you miss the actress, then get ready, because she's set to star in the upcoming "The Hills: New Beginnings."
