The "Up" series of documentary films follows the lives of fourteen British individuals since 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.
