The Up series of documentary films follows the lives of ten boys and four girls in England, beginning in 1964, when they were seven years old. The first film was titled Seven Up!, with later films adjusting the number in the title to match the age of the subjects at the time of filming. The documentary has had nine episodes—one every seven years—thus spanning 56 years. The series has been produced by Granada Television for ITV, which has broadcast all of them except 42 Up (1998), which was broadcast on BBC One. Individual films and the series as a whole have received numerous accolades; in 1991, the then-latest instalment, 28 Up, was chosen for Roger Ebert's list of the ten greatest films of all time.
