Staircase (1969) is Donen's adaptation of the autobiographical stage play by Charles Dyer with music by Dudley Moore. Rex Harrison and Richard Burton star as a middle-aged gay couple who run a London barber shop and live together in a "bad marriage". The film was shot in Paris for tax purposes and was not a financial success. It received poor reviews upon release, but was re-evaluated by film critic Armond White in 2007. He called the film "a rare Hollywood movie to depict gay experience with wisdom, humor and warmth", and "a lost treasure".
