The Locket (1946)

Fans of Hitchcock's 'Spellbound' and 'Marnie' with really enjoy 'The Locket', an unfairly overlooked b-grade noir starring Laraine Day (who co-starred in Hitchcock's underrated 'Foreign Correspondent'). The direction (by John Brahm) isn't all that Hitchcock-esque but the subject matter is. Day plays a woman on the eve of her wedding whose husband is approached by a man warning him off marrying her. He tells his story in flashback, and then the flashback has a flashback and so on. Day gives a brilliant performance and the king of cool Robert Mitchum plays one of the three men in her life (the other two are Brian Aherne and Gene Raymond). This movie is very highly regarded for some inexplicable reason but I thought it was fascinating. Mystery and Noir fans with lap it up. Well worth watching if you get the chance.
