Director Jack Gold did not want Richard Burton and instead suggested Nicol Williamson for the lead role. The producers told him it would be easier to get funding with Burton, who had just made his "comeback" film Equus (1977).
The film was made two years after its source novel of the same name by Peter Van Greenaway had been first published in 1975. The movie is the only ever theatrical feature film adaptation of one of Greenaway's books.
The tower block in the plane crash sequence was made out to be "Centre Point", a tower which had been empty since it was built in 1964. It still exists today by Tottenham Court Road and New Oxford Street. It is one of the tallest concrete towers in Britain (117m) and nominated as one of London's ugliest structures. It has been home to the Confederation of British Industry since 1980.
