The Secret Fury works best if one is willing to suspend one's disbelief from the outset. Claudette Colbert stars as Ellen, a famed concert pianist who, on the day of her wedding, is accosted by a stranger who insists that she's already married to someone else. Ellen is willing to laugh this off, until the stranger produces witnesses, records and the justice of the piece. Has Ellen lost her mind, or is she merely the victim of an elaborate scam. With the help of fiancé David (Robert Ryan), Our Heroine begins her own investigation -- and ends up accused of murder and shunted off to a mental institution. And the story isn't over yet! Featured in a pivotal role is future I Love Lucy co-star Vivian Vance, who'd previously worked in an L.A. theatre company with Secret Fury-director Mel Ferrer. For reasons best known to himself, Willard Parker, a fairly well-known film actor in 1950, appears unbilled.
