After training in acting and dancing , she took a part as a school girl in STV 's production of '' The Prime of Miss Jean Brodie '' where she was credited as Dory Hepburn . She starred in the 1981 film '' Gregory 's Girl '' playing John Gordon Sinclair 's love interest Dorothy , for which she won the Variety Club actress of the year award . Unlike most of the cast , who were sourced from the Glasgow Youth Theatre , Hepburn was spotted by Bill Forsyth dancing in a television commercial for a Scottish department store . The film 's cast reunited for the 30th anniversary of its release in 2010 , and a clip from the film featuring Hepburn was part of the opening ceremony from the London 2012 Summer Olympics
