Been searching for this movie, for weeks! NO.. For years! Here is the plot.. very vague, but this is the best I can do.

There's this adult guy(main character).. HEROIC. His weapon is a sword(I think?) Then there's this little boy, he's been attacked by an unknown enemy, ALIEN? Or something. He's been pulled under the desert, anddd of course he was saved by the main character.

I've watched this movie when I was 5-7 years old, and now I'm 15 years old. It's an American movie. The film is 80s.. I think? This movie has LOTS OF ACTION, that's for sure.

AND OH YEAH, I remember, there's this scene, when the main character entered a bar, there's this belly dancing girls..

I remember watching it on Cinemax channel
