A while back I got the Eurocrypt of Christopher Lee Volume I boxset that Severin put out.
As you can guess the set contains films Lee did in Europe, I do believe three of the movies in this set were filmed while Lee was in Italy for three months!
In Challenge the Devil, also known as Katarsis and also Sfida al Diavolo, Lee plays the Devil/Lord of the Castle.
He is also in this film probably in total give or take around ten minutes! I have read that Lee states he was only on the set for about a week and never saw the film afterwards.
The plot is about a group of people who seem to live a rowdy lifestyle of drinking and not caring about others and pretty much causing trouble. They end up in at a castle where they meet Lee's character who has them explore the castle for a woman, in which they are haunted and forced to realise their errors and to try become better people.
The story is told by one of the gang who has now due to his experience became a monk and is now himself trying to help a friend come to her senses and do the right thing....
This film is ok, not exactly amazing and think they definitely tried to cash in with having Lee in it as a big star to draw people in.
Also, the film starts off more like a crime thriller then slowly moves into a weak gothic horror. There is a scene which feels more like it was set just to highlight a singer which to me doesn't add to this film, if it was cut it may have helped the film flow a bit better as I did think at times it dragged.
It is also worth noting that this film was sort of missing for nearly 50 years, not because negatives were lost but because it was that bad that it was more likely hidden away. But I guess it maybe one for the Christopher Lee completists but be prepared that it is not that great!
