When Mary Kate and Ashley Olsen's first TV movie trounced "60 Minutes" in the ratings, their lawyer, Robert Thorne, negotiated a deal whereby the sisters would supply movies to the network through their own production company. The sisters, the youngest producers in Hollywood, were just six years old.
[In March 2003, the Olsen twins signed a 10-record deal with Columbia -- simply to re-release music which they recorded in their "Full House" days (including such hits as "I Am the Cute One" and "Brother for Sale").]
