Sometime in the 80’s I remember watching a movie (not sure if it was tv or film) and it involved a boy and his interaction with a character which was essentially talking lips (like the Rolling Stones) and there was no eyes or nose. At some point I remember the boy going into a tree or a room of some sort that was completely blank (no background) and having conversations with this talking lips character. This the the only movie in my life I have never been able to identify. Please help!!
