A London to New York flight carrying an ancient Druid sacrificial stone in its cargo unleashes a demon that terrorizes the passengers and crew. One's tolerance for this sort of thing depends on one's appetite for schlock ..... mine's insatiable! It's AIRPORT meets THE HAUNTING. The passengers are an inane group played by a LOVE BOAT type "B" cast. There's William Shatner as a defrocked priest, Tammy Grimes as a whacked out witch, Buddy Ebsen as a billionaire, Chuck Connors at the pilot, Paul Winfield as a doctor, France Nuyen as a model etc. The characters do the most ludicrous things and a scene where the passengers dress up a little girl's doll and try to pass it on to the demon for a human sacrifice has to be seen to be believed. The acting is dreadful (especially Ebsen and Shatner) though Grimes' hysteric is amusing. It's the kind of movie that, if you're game, can be fun in a bad movie way. Directed by David Lowell Rich (THE CONCORDE AIRPORT 1979). With Roy Thinnes, Jane Merrow (THE LION IN WINTER), Russell Johnson (GILLIGAN'S ISLAND), Lynn Loring (doing an imitation of Mia Farrow), Will Hutchins, Darleen Carr and Brenda Benet.
