Stretching the Airport concept as far as it will go, this third film in the series sticks a jet full of old actors 50 feet underwater in the Bermuda Triangle. Oxygen (and credibility) grows short, and Jimmy Stewart plays an art collector targeted for a heist.
Jack Lemmon is the unfortunate pilot, and Christopher Lee shows up along with Brenda Vaccaro, Joseph Cotten, and Olivia de Havilland. Jerry Jameson, auteur of The Bat People, was selected to helm this entry featuring that film's star, Michael Pataki. George Kennedy, the only man to appear in all four Airport films, is along for the ride as well.
