Although slightly more melodramatic, I feel this does have the edge over the later, 'Criminal Life of Archibaldo de La Cruz', which covers similar territory with more humour. A gripping and frightening tale of obsession that has a surprisingly large amount of echoes of Hitchcock's later, 'Vertigo' and seemingly that director took the bell tower sequence in its entirety. Still, who cares, great films remain great films, even when their inspiration may be revealed. The ending is low key but we are left in little doubt as to the state of mind of our hero/villain. Great performances help what might have seemed a preposterous tale, ring only too true. Probably best watched after Archibaldo, then the impact will be all the more great.
