Routine airline flight, piloted by none other than Charlton Heston, is beset with hijack warnings via notes left on the lavatory mirror. Could the psycho-on-board be musician Roosevelt "Rosie" Grier? Sweaty soldier James Brolin? Hippie Susan Dey or boy toy Nicholas Hammond? What about distraught stewardess Yvette Mimieux--has she cracked under pressure? Genre disaster flick slipped into theaters in between 1970's "Airport" and its many sequels, and actually was quite a hit at the box-office (but in this era, what Charlton Heston movie wasn't?). Unfortunately, once all is revealed--in rather anticlimactic fashion--the last reel is extremely dire. Still, for the first three-quarters of its length, "Skyjacked" provides just the kind of silly thrills you'd expect from a movie with that title and cast. Speaking of titles, "Skyjacked" was RE-TITLED "Sky Terror" once it premiered on network television. No sense frightening anyone into thinking this might be a documentary. ** from ****
