I need the name of a movie that came out in either the 80s or early 90s. I seem to remember it being a kids movie, but I could be wrong. It involved a group of kids and a robot companion, the robot was shaped identically to R2-D2, except I think that he might have been painted red instead of blue, and he had a detachable head that could hover around. I think that the robot "died" by getting lowered into a pool or vat of some acid, but the floating head survived. The details are all very fuzzy, but that's the gist of it, I think.

Too Much (http://www.imdb.com/title/tt0094164/)
The scene with the pool/head is mentioned in this review: The Golan-Globus Movie Too Much (http://www.the-wabe.com/reviews/too-much.html)

Quinn, you are a god among men. I'm mean, really, how do you find these things? In all honestly, I kind of wish you hadn't, because that movie is complete garbage, but it's nice to know I can trace me B-Rated loce back to childhood.

Lol, that's often the way it is. Glad to help.
