The Big Bluff (1955) John Bromfield, Martha Vickers and Robert Hutton

The suave Don Juan Ricardo Rick De Villa (John Bromfield) and his married lover Fritzi Darvel would like to take off together, but his lack of money prevents them from doing so. A chance encounter introduces Rick to the young but terminally ill socialite Valerie Bancroft (Martha Vickers), in whom Rick sees the solution to his predicament. Rick sweeps her off her feet and they soon marry, although Valerie s entourage is suspicious of him. Rick then proceeds to try to bring about Valerie s demise so he can inherit her wealth and live the good life with Fritzi.
