Curtis Harrington directed this somewhat neglected 1967 thriller, which stars a pre-Godfather James Caan, and a just-pre-Graduate Katharine Ross, as a wealthy, somewhat twisted couple who engage in increasingly elaborate and sinister mind games. Simone Signoret co-stars as someone else drawn into the “fun,” which descends quickly into the macabre, and possibly even to murder. Games rarely is televised, so take this late-night opportunity to watch or record it.
