I saw it on BBC TV in 1977 before video recorders unfortunately,it is well acted there is good chemistry between the stars adding to sufficient tension. Scott Walker recorded the theme song, I can't find that either' it's memorable! with regard to films about lesbianism this cannot be seen as positive because it does not have a good ending, but if Anne Heywoods character is seen as bisexual It's admissible. The entertainment value is excellent and there is no gratuitous sex. Lets hope it emerges somewhere, In a charity shop maybe! I heard the BBC were going to concentrate on Twentieth century writers maybe someone working for them reading this could give them a nudge, though they might think the Fox to dated to make in today's slightly more liberal climate
