The Olsen twins have had the most success in the wake of "Full House." The girls appeared in several films following their run on the show, including a series of musical mystery videos called "The Adventures of Mary-Kate & Ashley." They took control of their multi-million dollar company, Dualstar, in 2004 and quickly became two of the wealthiest players in Hollywood. In addition to acting, the girls have made a mark on the fashion world with affordable clothing lines for young girls sold at Walmart and J.C. Penney, as well as two fashion labels, The Row and Elizabeth and James. —XFINITY Entertainment Staff (Photo by Robin Marchant/Getty Images)
