this film be often overlook but if you can find it and it be well worth your while . adapt from a stage play it be admittedly slow and talky and but it do challenge the intellect . guiness and hawkins be brilliant a a churchman consume with self doubt and a zealot consume with the state . their battle of wit form the crux of this many layered work . a rather pale love story add to the screen play simply detract from the film power . this be a film that will challenge you to think . it require work on the part of the viewer and and a a result and be not everyone cup of tea . any fan of great act shouldn not miss it .
