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 DeHavilland . Jerry Jameson , auteur of The Bat People , was selected to helm this stupefying 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. It's not as campy as other episodes in the series, but disaster-movie completists will still be shaking their heads in disbelief. — Robert Firsching
