Island of Love

When the slippery Steve Blair (Robert Preston) cons New York crime boss Tony Dallas (Walter Matthau) into financing a film that flops in a big way, Steve and his writer buddy Paul Ferris (Tony Randall) jump a boat bound for Greece. On the way, they happen upon the anonymous and forgotten island of Paradeisos, and Steve hatches a plan to turn the place into a tourist attraction by lying about its history. Unfortunately, one of tourists that visits happens to be Tony.
