The Day the Earth Froze is a Russian-Finish film that goes by Sampo. It was bought by American-International Pictures, cut by 24 minutes, the crew was renamed (Aleksandr Ptushko is Gregg Sebelious,  Eve Kivi is Nina Anderson and Andris Oshin has the name Jon Powers) and it was a double feature with Conquered City. There’s also the idea that this was shot in Vistascope, whatever that could be.

It’s all about how Lemminkäinen tries to win the heart of Annikki and battles the evil witch Louhi, who wants to make a magic machine called a Sampo that can make salt, grain and gold. When our hero fails to get it for her, she steals the sun and the world freezes, just as you’d expect from the name of the movie.

Directed by the same man who made The Magic Voyage of Sinbad and The Sword and the Dragon, each scene was shot four times: once in Russian, once in Finnish and then in both standard and anamorphic widescreen

If you have only seen the Mystery Science Theater 3000 version, well, you can get the original film in a restored version from Deaf Crocodile. You can also watch this on Tubi.
