Seven Up!

The Up Series is a series of documentary films that have followed the lives of fourteen British children since 1964, when they were seven years old. The children were selected to represent the range of socio-economic backgrounds in Britain at that time, with the explicit assumption that each child's social class predetermines their future. Every seven years, the director, Michael Apted, films new material from as many of the fourteen as he can get to participate. Filming for the next installment in the series, 56 Up, is expected in late 2011 or early 2012.

The first film in the series, Seven Up!, was directed by Paul Almond, and commissioned by Granada Television as a programme in the World in Action series broadcast in 1964. From 7 Plus Seven onward the films have been directed by Michael Apted, who had been a researcher on Seven Up! and chose the original children with Gordon McDougall. The premise of the film was taken from the Jesuit motto "Give me a child until he is seven and I will give you the man," which is based on a quotation by Francis Xavier. The 1998 programme was commissioned by BBC One, although still produced for them by Granada.
