Orrore a 12000 metri

A familiar cast of TV veterans star in this entertaining, reasonably effective TV movie that stars Roy Thinnes("The Invaders") as an architect transporting an old Abbey altar on an airplane from London to L.A. that comes to demonic life, threatening all aboard, like William Shatner("Star Trek") as a former priest called back into action to defeat the evil, and Chuck Conners("The Rifleman") as the pilot. Buddy Ebsen("Barnaby Jones") and Russell Johnson("Gilligan's Island") costar.

Interesting coincidences here: both Shatner and Johnson starred together on an excellent episode of "Thriller" called 'The Hungry Glass', and Shatner also memorably appeared on "The Twilight Zone" as a similarly tormented man('Nightmare At 20,000 Feet') Both Shatner and Conners would later costar in spoof "Airplane II: The Sequel"

Just out on DVD, and worth a look.
