本部纪录片是导演迈克尔·艾普特从1964年开始拍摄的纪录片系列的第三部。迈克尔·艾普特在1964年为英国BBC电视台拍摄了记录片《7 Up》，采访来自英国不同阶层的十四个七岁的小孩子，他们有的来自孤儿院有的是上层社会的小孩。此后每隔七年，艾普特都会重新采访当年的这些孩子，倾听他们的梦想，畅谈他们的生活。正值青春年华的孩子们，已经长到21岁。当年导演的初衷是批判英国社会阶层的不可改变性，穷人的孩子还是穷人，富人的孩子还是富人。在时隔数十年之后，这一点初得印证。可生命的无偿又岂会就此止步。 　　本部系列纪录片，跨越半个世纪，史无前例地记录了真人版的“人生七年”。

Born in the USSR: 21 Up is a 2005 British documentary, directed by Sergei Miroshnichenko. 　　Following in the tradition of the original UK Up Series, this documentary revisits a group of Russian children at seven-year intervals to track their development against a backdrop of social and political change. Following the success of the UK original, this film looks at life for a group of young people from the former Soviet Union. The adults here, all introduced to viewers at the age of seven and seen again at 14, were born in a country that no longer exists. Their stories provide an insight into the break-up of the former Soviet Union as well as a reflection of what life has become without Communism. 　　Since filming started 14 years ago, some of the youngsters have left the former USSR to go to Israel or the United States, some have stayed in their family home, but all have had their lives changed. Archival footage of them at the ages of seven and 14, and now new material at 21, shows life in a society that was once shut off from the world. 　　The documentary was followed by Born in the USSR: 28 Up in 2012.
