High Seas Hijack on AllMovie

Five years after Mission: Impossible, Peter Graves accepted a starring assignment in the modestly budgeted High Seas Hijack. Most of the film takes place on a highly valuable oil tanker. A group of terrorists decide that the best way to advance their cause is to steal the tanker and imprison its passengers. Their tactics are just as brutal and bloodthirsty as the pirates of old, but the good guys manage to dish it out as well as take it. High Sea Hijack is distinguished by the presence of Gigi Perreau, a former child actress who seldom showed up on screen after 1961.
