Synopsis by Hal Erickson
Port Sinister was produced by the team of Aubrey Wisberg and Jack Pollexfen, whose chief claim to fame was the 1951 sci-fi "sleeper" The Man From Planet X. Soldier of fortune Tony Ferris (James Warren) leads an expedition to an island threatened with extinction by a volcano. No, Ferris isn't crazy: it is his belief that the eruption will reveal a fortune in buried pirate treasure. Surrounded by highly suspicious-looking characters, Ferris can trust only his longtime companion, Jean Hunter (Lynne Roberts) -- and even she doesn't seem too trustworthy. Originally distributed by RKO Radio, Port Sinister was re-issued by Realart Pictures in 1961 under the title Beast of Paradise Isle.
