Valhal (Valhalla) A Danish animated film from 1986. The story follows a brother and sister on an adventure with Thor and Loki to meet with Odin. I wish I could speak Danish, but I’ll just have to see if I can follow along.
This was one of my favorite movies growing up - a very dark movie considering it’s intended audience, although that may be why I like it so much. I’m 22 and I still love it!
