From 'Beverly Hills, 90210' to Stardom - 10 Pre-Famous Show Appearances

Beverly Hills, 90210 ran for 10 seasons on Fox from 1990 to 2000, launching several actors to prominence and numerous spinoff series with Melrose Place (1992-99), Models Inc. (1994-95) and 90210 (2008-13). But you probably don't remember these 10 stars who appeared on the original 90210 before they made it big.

Jessica Alba (Leanne) '98

Jessica Alba appeared in two season eight episodes in 1998 playing the part of Leanne, a pregnant teenager in need of help. She pays a visit to the urgent care facility where Kelly Taylor (Jennie Garth) works but ultimately abandons her newborn baby in a dumpster. Despite Leanne's immaturity, Kelly attempts to take care of the baby herself before ultimately giving it up for adoption. Alba went on to star in the TV series Dark Angel from 2000 to 2002 and has appeared in numerous blockbuster films including Sin City, Fantastic Four, and Little Fockers.

Denise Richards (Robin McGill) '92

In 1992, Denise Richards had a bit part playing Kelly Taylor's cousin Robin McGill in the season two finale. Robin is in town attending her aunt's wedding when she meets Steve Sanders (Ian Ziering). After a brief exchange -- and some heavy flirting -- Steve and Robin walk off together arm in arm. Richards was famously married to bad boy Charlie Sheen from 2002 to 2006. She's appeared in several films including Wild Things, Drop Dead Gorgeous and The World Is Not Enough, and she starred in her own reality show, Denise Richards: It's Complicated, from 2008-09.

Hilary Swank (Carly Reynolds) '97, '98

Before she was an Oscar-winning actress, Hilary Swank played Carly Reynolds in seasons eight and nine. Carly is a college dropout with a 6-year-old son named Zach when she meets Steve Sanders. Carly eventually falls for Steve and they begin dating, with Steve quickly developing a fatherly bond with Zach. When Carly's father falls ill, she and Zach must move back to Montana, which effectively ends her relationship with Steve. Swank received her first Academy Award in 2000 for her performance in Boys Don't Cry, and in 2005 she won her second Oscar for her portrayal of a struggling boxer in Million Dollar Baby.
