Seven Up - Thirty Five

Nick

Nick was raised on a small farm in Arncliffe, a tiny village in the Yorkshire Dales. He was educated in a one-room school, and later at a boarding school. He went to Oxford University and then moved to the United States to work as a nuclear physicist. He married another British ex-pat, who participated in 28 Up but was displeased with how her comments were received by viewers, many of whom apparently concluded that the marriage was doomed. She declined to appear in 35 Up and 42 Up. By 49 Up the couple had divorced and Nick had remarried. Nick is currently a professor at the University of Wisconsin-Madison in the Electrical and Computer Engineering Department. 

Peter

Peter went to the same middle-class Liverpool suburban school as Neil and, at seven, both wanted to be astronauts. Peter drifted through university, and by age 28 he was an underpaid and seemingly uninspired school teacher. Peter dropped out of the series after 28 Up, when he lost his job as a teacher following a tabloid press campaign against him after he criticised the government of Margaret Thatcher in his interview. He is in a Liverpool-based country-influenced band called The Good Intentions.

Neil

Neil turned out to be the most unpredictable of the entire group. At seven he was funny, full of life and hope. By the time of 21 Up he was homeless in London, having dropped out of Aberdeen University after one term, and was living in a squat and finding work as he could on building sites. During the interview he is clearly in an agitated state, and it becomes apparent that he has mental health issues and is struggling to cope with life; he mentions he had had thoughts of suicide. At 28 he was still homeless, although now in Scotland; by 35 he was living in a council house on the Shetland Islands, off the north coast of Scotland, writing and appearing in the local pantomime. By the time of 42 Up he had finally found some stability in his life (with some help from Bruce--he was living in Bruce's apartment in London and Bruce had become a source of emotional support) and was involved in local council politics, as a Liberal Democrat in the London Borough of Hackney. By the time of 49 Up, he is a District Councillor in the Eden district of Cumbria, in North West England.

Bruce

Bruce was an idealist who was concerned with poverty and racial discrimination and wanted to become a missionary. He was attending a prestigious boarding school. At the age of seven, he said that his greatest desire was to see his father, who was living in Rhodesia, and he seemed a little abandoned. Bruce studied mathematics at Oxford University and used his education to teach children in the East End of London and Sylhet, Bangladesh. Before 42 Up, he married, and Apted broke the seven-year structure of the films to film Bruce's wedding, which was also attended by Neil. Eventually becoming burned out with teaching in the East End, Bruce currently teaches at St Albans School, Hertfordshire, a prestigious public school. Between 42 Up and 49 Up, he had two sons, and is happily married to a fellow teacher.
