The Olsen twins grew up in the spotlight, but Ashley, left, and Mary-Kate, right, aren't the only talent in the family. Now, little sister Elizabeth is launching her own film career with the new indie flick "Martha Marcy May Marlene," about a young girl who escapes from a cult. The fest favorite is already generating major buzz for the budding star. The twins, of course, have been on screen since they were in diapers on the set of "Full House" and went on to star in numerous films and TV movies. They even have their own Dualstar production company and a lucrative fashion line.

The Olsens, who have an older brother, Trent, aren't the first siblings to share the spotlight. Here's a closer look at some of Hollywood's most famous brothers and sisters.
