HOOP DREAMS, which dates from 1994, is an extraordinary documentary which covers four years in the lives of its subjects, a pair of inner-city Chicago youngsters who yearn for stardom on the hardwood. Well, a new-to-DVD documentary, titled 56 UP, is the latest in a series of films which, in their totality, cover 49 years in the lives of their subjects. They are a group of British youngsters from various classes and backgrounds who first were filmed as seven years olds in 1964. Every seven years, the cameras have been turned back on and they have been revisited and filmed yet again. A bit of simple math tells us that 56 UP is the eighth installment in the series.
