Most of us have snapshots of our lives, records of the first day of school or the prom. "56 Up" is director Michael Apted's record of the lives of 14 Britishers tells their stories, albeit in brief, through film. "56 Up" continues what he started in 1964 when he first interviewed 10 boys and four girls, each age 7. Its cutesy title was "Seven Up," which explains the current title and those of films in between, shot at seven-year intervals.
