Michael Apted on His Documentary Subjects Nearly 50 Years Later

Michael Apted directed the Bond film "The World is Not Enough." He gave us "Coal Miner's Daughter" and "Gorillas in the Mist." But perhaps his most fascinating work started half a century ago -- the "Up" series, documentaries about a group of British children. It began in 1964 when they were 7 years old, and every seven years, there's been an update. The "kids" are middle-aged now. The latest installment, "56 Up," opens Friday.
