I've have always wanted to watch this Richard Burton and Rex Harrison-starred film, Staircase (Dir: Stanley Donen, 1969), although it seems to be hard to come by. Staircase was one of the films that Hollywood put out in the late 1960s to cash in on the new acceptance of homosexuality as an open topic, although from today's perspective it still looks very biased. Reflections in a Golden Eye, with Liz Taylor and Marlon Brando, is another example of this mini-crop of films. Brando plays a closeted major married to Taylor's slutty Leonora...hhmm).
Prejudices aside, Staircase does look fun, though, and I have heard good comments about the acting. The story? Charles Dyer (Harrison) and Harry Leeds (Burton) are a couple that have been living together for nearly 20 years. Both earn a living as hairdressers (what else?) in the West End of London and both care deeply for their mothers (surprise, surprise), but not each other as time apart takes its toll on their relationship when Harry has to care for his invalid mother who snips at him every chance she gets. The script was written by Charles Dyer.
