First broadcast in 1964, this is an engrossing chronicle of the lives of 14 students from varied social backgrounds (in England), beginning when they were 7 years old. The first meeting with the group of wide-eyed, innocent children invites viewers to take a look at lives in the making; the follow-up film, 7 Plus Seven, checks in on them 7 years later.
The latest, 49 up, checks in on them at the age of 49. Fascinating stuff!
