Here’s the YouTube description:
Rubber Johnny is a 6 minute experimental short film and music video directed by Chris Cunningham in 2005, using music composed by Aphex Twin.
The concept for Rubber Johnny came from Cunningham imagining a raver morphing as he danced. The idea evolved to the present film, in which **Johnny (played by Cunningham) is an isolated mutant child with a huge overgrown cranium, strapped into a wheelchair and locked in a basement. Capable of morphing his body, he spends his life trying to amuse himself and his dog, a terrified chihuahua. **
The very beginning is awful.
