Beverly Hills, 90210

Guest stars were abundant, and the show helped launch many careers. Grant Show (whose character helped launch the spin-off "Melrose Place"), Jessica Alba and Matthew Perry all made appearances. Hilary Swank is by far the most successful actress to come out of the show (do you ... moreknow why she left?), but many, including Shannen Doherty, Jennie Garth, Tori Spelling and Gabrielle Carteris, have all moved on to some type of a reality show.
