Kennedys open up for TV documentary on RFK's widow


The Kennedys may be America's most famous political dynasty, but it took one of their own to get them to open up about their private lives and their place in U.S. history.

Filmmaker Rory Kennedy, 43, the youngest of the 11 children of slain U.S. Senator Robert F. Kennedy, and his wife, Ethel, persuaded her mother to give her first extended interview in more than 20 years for an upcoming HBO documentary that is also the first film about the Kennedys to come from within the family.
