I think the movie is called The Cube. I was flipping through channels one night and stumbled upon it on the scifi station. I watched it from about half way through all the way to the end. All that it was, was some people crawling through a giant cube into another cube, into another cube, into another cube... and each cube was identical to the last.
It was one of those movies that I found myself being amazed at how stupid it was, yet I couldnt stop watching it for that very reason.
