This is a movie I would always see on cable when I was little, and its pure wtf:
Mel Brooks executive produced it, it made $1,579,260 at the box office on a budget of $7,500,000, and it ended the directing career of the director.
This IMDB review best sums it up:
"Are children lovable prisoners of a Nazi-Fetish, post-apocalyptic corporation/government agency that inexplicably decides to profit by running a child-labor camp in the desert? Check. Are the children also forced to play an arena sport involving roller skates? Check. Does a glowing alien ball appear randomly and befriend the children, with no apparent connection to anything else in the film? Check. Do the children breakdance with the glowing alien ball-friend? Check. Does the glowing alien ball require the children to escape the prison and go on a quest? Yep. Do the children "escape" simply by roller-skating away from the "prison" (through a desert)? Um, yes. Does the glowing alien ball-friend require the children to join hands in a ritualized new-age circle of friendship/love in order to achieve its full glowing alien ball powers? You betcha."
You guys should totally do it! (It's also on Netflix Instant)
Edit: apparently the whole thing is on YouTube as well:
