This is the first Lego animation (first proper one, there were technically a few before it without minifigures) ever made, by an Australian animator named "Lindsay Fleay".
It was created in Perth, Western Australia between the years of 1985 and 1989!
I talked to Lindsay and he gave me permission to upload this to my KZread channel.
Normally I wouldn't upload someone else's work, but I had to spread the word on this classic.
Here's the blurb from Lindsay's website: www.rakrent.com/
"The Magic Portal is a short stop motion film that uses LEGO®, plasticene, cardboard and pixellated live action, made between the years of 1985 and 1989 on good ol' fashioned 16mm film. The story concerns the strange fate of a LEGO astronaut called L, who discovers the Magic Portal on board his giant spaceship. The Portal takes him to a strange and surreal LEGO world where he has a close encounter with a Monster and barely escapes with his life. His report to Captain Paranoia only gets him to trouble and his friend and shipmate P, doesn't believe him. However, the Portal has a mind of its own, and reappears to upset the cosy world of the giant spaceship and its crew to reveal weirder worlds more peculiar than the last..."
