Two members of the cast of The Real Housewives of Beverly HillsKim and Kyle Richards, both half-sisters of Kathy Hilton — were child stars in the '70s. Certainly, when you and your sister have appeared in myriad shows and movies, your lives are bound to have a certain level of glamour. Then again, when your cumulative resumes include a starring role in the sitcom Hello, Larry, which TV Guide panned as the 12th worst show of all time, and an appearance in the horror movie The Car (about — you guessed it! — a killer car), let's just say no one is going to mistake your family for the Barrymores.

Nonetheless, the Kim and Kyle's Hollywood careers have had their high points. As a young girl, Kim was the face of Disney — sort of her generation's Hilary or Miley. She starred in the film Escape from Witch Mountain (and its sequel), as well as scores of Disney's made-for-TV movies. After breaking with the Mouse, she enjoyed a recurring role on Diff’rent Strokes in 1979 (meaning she knew Gary Coleman!), and she appeared in the mid-'80s comedy Meatballs II.

Faced with a stalling career, she "retired" in 1990. But, similar to Jay-Z, retirement didn't stick: Over the past few years, she's taken on several bit film roles including a cameo in the Race to Witch Mountain, a Disney remake starring The Rock. Yes, her resume is rife with the words "witch" and "mountain."

Her sister Kyle has had a slightly more active career. Highlights include a part in Halloween, a year-long stint on Little House on the Prairie, and more recently a recurring role as Nurse Dori on ER (meaning she knows John Stamos, which isn't quite as cool as knowing Gary Coleman, but it's still pretty nifty).
