I want to know the name of this movie but I don't remember much of it. I know its on another planet or in the future.
There's this scene, I guess the hero was captured by his enemies and he has to put his hand on a rock with some holes, the problem is if he chooses the wrong hole there's a mortal creature inside and it would bite him.
There's another scene I remember, the hero uses a sort of car that rides in a rail( I guess it was white and looked somehow like the DeLorian of "Back to the Future").
If anyone could help. Thanks!

This sounds an awful lot like the movie Flash Gordon.

Flash Gordon (1980) (http://www.imdb.com/title/tt0080745/)

AND that movie had a completely kick- uber-cheesy soundtrack by Queen.

I was 4 or 5 years old when I watched it. Going to check it out and see if its as good as I thought it was.
:D
Thanks a lot!

Not certain but it could be "THE HAND" starring Michael Caine. Let me know if this is right or not. Cheers

Just watched Flash Gordon.
The first scene I described is actually from it. But, the second is not.. :(

I still wonder which movie is that other one...
:confused:
Thank u guys anyway.
