This was a minor studio production but has become a B film legend. Julia (Nina Foch) takes a job as a secretary to a family of nutcases who kidnap her and lock her up on a remote estate in Cornwall (shot in California). They need a body to stand in for the woman who was murdered by her psychopathic husband, which will be made to look like a suicide.
They parade Julia as the wife for the benefit of local witnesses, claiming her protests are part of her psychosis. OK, it's a screwball story, though no more than many other golden age mysteries. It succeeds because Joseph H. Lewis stages it so well. No screen time is wasted, and there's one of the most brilliant noir house-of-shadows.
Nina Foch is believable in the difficult title role, but it is the crazy abductors who make a bigger impression. May Whitty is the eccentric but ruthlessly pragmatic mother of the simple-minded George Macready. He is splendidly menacing as the killer who relishes their plans for Julia, while also enjoying having her as his wife, for a while.
It is set in England, where in the world of Hollywood these things happen. Like Gaslight. Film fans like to flag up the doomed males of film noir, exploited by a predatory female, as a key postwar theme. But there were many women like Julia; lonely, vulnerable and manipulated, particularly by family. My Name is Julia Ross is among the most typical and successful of these.
