This movie is BEGGING to be riffed. There's a user review on IMDB that says everything that needs to be said:

A Great B-Movie
iaido23 January 2000

I saw this movie last night on TNT's Monstervision with Joe Bob Briggs, and, considering myself to be a fairly good b-movie buff, I was quite surprised I had never come across this movie before. It has to go down as one of the better third rate action movies of the 80's (think Gymkata, and so on); highly ridiculous plot, cheap production, cardboard acting, but a whole **** of a lot of fun and consistently entertaining.

To explain the plot would take a forever, and there are so many holes in it any way I would wear out my ? key. But, roughly, here is what the movie has to offer- A magic spear, time traveler, biker gang, Nazis, kung fu tour guide, kung fu master, Asian mobsters, Mongol warriors, cave dwelling midget Mongols, Amazon women, a Pit of Death, earthquakes with Styrofoam boulder tossing, a car chase that is at night one minute then during the day the next, improbable helicopter sabotage, two people one parachute parachuting, Bonehead Nazi henchmen, four midgets pound a Nazi to death, a whole lot of spear chucking, alligators chomping on Amazons, a very decent kung fu fight, and even more.

Highly, HIGHLY, recommended for the b-movie fan. I could watch it over and over again it is so gloriously bad.

Please, pretty please with cherries and bonehead Nazi henchmen on top, RIFF THIS MOVIE.

I just saw Future Hunters and thought very much of how good of a fit it would be for RiffTrax. And that doesn't happen with every bad movie I watch.

This movie is a genre blender: Mad Max, time travel, kung fu, Romancing the Stone, Indiana Jones, Illinois Nazis, Amazonians, and a cave dwelling tribe of little people. ... Uh, is that a genre?

This is the first movie of Robert Patrick, of T2, X-Files, and etc. fame. There is plenty of riffing opportunity with his over-excited virgin performance and his tidy whities scene. ... It also has Rob Schott, which should at least be good for an oldschool 'Gykata!' or two. .. There is some nice Kung Fu between Bruce Le and Jang Le Hwang, both 10 years into their martial arts movie careers. But more importantly there is some crazy ADR in at least one of the Hong Kong scenes. ... Oh, and don't miss the Amazonian who gets a boulder upside her head, that poor actress.

There is part of one scene with toplessness where the lead female character is being threatened.
But that could get cut out of a RiffTrax edit. Other than that the movie doesn't really come across as sexist or degrading toward any group in particular. ... Well, Nazis whose aim is global societal manipulation through a plan entirely dependent on possession of a spear tip that pierced Jesus when he was on the cross, those guys come out looking like some real jerks.

So to recap: crazy rambling story, bad editing, over-the-top characters, familiar faces, genre referencing goldmine, and top it all off with an ending that just kind of ... ends. Seriously, you guys should be riffing this.

** I've watched everything RiffTrax has done ... except I won't watch a riffed Casablanca. **

The opening paragraph spoken by the narrator says it all:

"It is the year 2025, almost 40 years since the great holocaust. A once proud world has been reduced to ruin, famine, and despair in the bitter aftermath of war. Now mankind's last, frail hope lies in a fabled object which has the power to turn back time and perhaps to undo the evil which has befallen the world."

Here's where it gets good.

"That object is the spear of Longinus. The spear which pierced the body of Christ on the cross and which holds the very power of creation itself. In a desperate attempt to find the spear and journey back in time to prevent the holocaust, a small band of rebels has crossed deep into the forbidden zone."
