The Great Alligator (1979) [Blu-ray]

At the opening of a tropical resort, a photographer (Claudio Cassinelli of SLAVE OF THE CANNIBAL GOD), an anthropologist (Barbara Bach of THE SPY WHO LOVED ME) and an arrogant hotelier (Mel Ferrer of EATEN ALIVE!) are besieged by hostile natives, obnoxious tourists and a gargantuan river beast that intends to devour them all.
