Sunday, Bloody Sunday (1971) DVD

Oscar winners Glenda Jackson, Peter Finch and John Schlesinger pool their talents for this remarkable, exquisitely photographed [and] almost perfectly directed film about two Londoners coping with the noncommittal affections of the lover they have in common.

Alex Greville (Jackson) and Daniel Hirsh (Finch) are deeply in love... with a young artist named Bob (Murray Head). And though Bob professes to love each of them, he moves freely between them, unencumbered by any sense of guilt. Realizing that their situation is a temporary comfort in an uncomfortable world, Alex and Daniel each grapple with their predicaments, she to face her fear of being alone, and he to come to terms with his homosexuality.
