Det Sjunde Inseglet is the (
Swedish) original title of the
movie that is known as
The Seventh Seal in
English.
It was made by
Ingmar Bergman in
1957 after a play with the same name and
author and is about a
knight returning to his
black plague-ravished home land after a
crusade. He plays
chess with
death and recites long
philosophical monologues. As the
writeup in
The Seventh Seal notes, it's
existentialist porn and maybe the
best movie ever made.
