The Easy Show Movie Projector needed a plain wall or a sheet suspended from a picture rail in order to work properly. I tried to view it on the ceiling once, but just got a cricked neck!
The Easy Show Movie Projector was battery operated and a strip of a 'movie' looking like a negative was slowly fed through it in order to shine on to the wall. There were lots of different films for it and 'current' cartoons like Popeye etc.
With the Easy Show Movie Projector you could pretend to be at the cinema - just without the popcorn stuck to your shirt and the annoying person with the huge hat sat in front of you!
