1950s

In an early role, Buckingham played the part of a saloon girl in the Jack Lee direct film Robbery Under Arms.^[1] In 1958, she played Mario's girlfriend in the comedy Next to No Time.^[2] In 1959, Buckingham played the eponymous role in the film Sapphire about a young woman found murdered on Hampstead Heath, but she did not have a speaking part and appears only briefly, as a dead body and in photographs.^[3][4][5]

1960s

Buckingham had prominent roles in two 1961 films, A Question of Suspense and Murder in Eden. As a result, she forfeited £4,000 which might have been paid from an insurance policy she took out in 1958 when she was aged 20, against failure to become a star within five years.^[6]

In 1962, she had a minor background role as “pretty girl” in the Neo Noir film, The Frightened City. In 1963, Buckingham played the lead role in The Keeler Affair, a film about Christine Keeler.^[7][8] Before Buckingham had secured the role, it was offered to Keeler who accepted it but because the Actors Equity did not accept her application, it meant that the other cast members could not perform with her.^[9]

1970s and 80s

In the late 1980s, she had a role in the Marcio Kogan, Isay Weinfeld directed film, Fogo e Paixão, which was a film about a bus tour through São Paulo where strange people are encountered. One of the tourists, a Japanese man called Kankeo (played by Ken Kaneko), filmed the event and shows it to his friends when he returns home.^[10][11][12]
