As a kid (I'm talking late 70's to early 80's) I remember watching a Sci-Fi/Horror flick that played on Saturday Cinema on regular television. The best description I can give is that a man & women walk into this dark building and these big blocks start moving & swinging at them. It's almost like an obstacle course. They have to duck and move or else get crushed by these amusement park - funhouse like machines. I distinctly remember the man getting crushed & his cracked wire rimmed glasses hitting the floor as the camera focused in on them. For some reason I know this movie left a lasting impression on me but I can only remember bits and pieces. Any help would be appreciated.
