Ten Little Indians (1967)

When a group of 10 strangers is invited to a party at a mansion in the Alps, each arrives expecting entertainment. However, a recorded message from their absent host informs them that each guest has been responsible for someone's death, and consequently each will be killed. Quickly, members of the party begin to turn up dead. American Hugh Lombard (Hugh O'Brian) and the beautiful Ann Clyde (Shirley Eaton) try to determine the identity of the murderer before they become the next victims.
