Two of a Kind (1951)

Lizabeth Scott is looking for the perfect patsy to impersonate a rich couple’s lost son and finds him in Edmond O’Brien. Despite all the hard work of her and her partner Alexander Knox, their scheme does not proceed as planned. The story unfortunately throws in the distraction of Terry Moore as a ditzy cousin of the lost boy and the ending wraps up in some too convenient ways, but the bits where Scott plays the manipulative femme fatale mostly makes up for the film’s weaknesses in its short runtime.
