The organization Mighty Jack is formed to combat the criminal syndicate known as "Q", and are given a large array of advanced weapons, chief among them being a high-tech submarine. Harold Hatari is abducted by Q, and Mighty Jack is dispatched to rescue him. Hatari is interrogated and threatened with blinding lights, but the Mighty Jack crew rescue him in the nick of time. Later, Q is discovered to be using "hot ice" (water that remains solid at room temperature) to create weapons and a secret ocean base disguised as an iceberg (though it's not precisely clear how hot ice could be a major world threat). Q then attempts to take over the Mighty Jack sub. Written by Leo L. Schwab <>

Did You Know?


When rockets are fired from the submerged Mighty Jack, the sound effect is that of rockets firing into the sky, not that of torpedoes being launched under water. Upon their detonation we also hear explosions that one would only hear in the open air. The sound of the laser cannon being fired and subsequent explosions continue this sound error. See more »

Make the hurting stop!
12 May 2000 | by (Northern CA) – See all my reviews

Apparently edited down from a Japanese TV series, "Mighty Jack" looks more like several completely unrelated spy films chopped up and reedited randomly. The plot, if it can be said to have one, is an exercise in incoherence. A plot synopsis is impossible for this film, *none* of it makes sense. What an endurance test this film is, anyone who makes it all the way to the end deserves some sort of medal.
