I recently watched Blu-rays discs of two animated films from Eastern Europe.
Delta Space Mission (1984) from Romania is a science fiction film. The plot and animation aren’t the best but the colors are wonderful. This would be great if you were on drugs. (The first movie I saw on acid was Fritz the Cat so I know what I’m talking about.)
The Old Man Movie (2019) from Estonia uses stop motion animation. It’s a very funny film about rescuing a cow before the udder explodes and causes a catastrophe.
