The Sorcerers is a 1967 horror film directed by Michael Reeves and starring Boris Karloff. It's good to see Karloff in the 1960's. This is an interesting film. Catherine Lacey plays Karloff's wife and is fascinating in the role. She does a great evil.
DVDTalk praises it, but reviews are hard to come by.
Because this blog does not consist of a single focus topic I chose the name Divers and Sundry where "Divers" means being of many and various kinds, and "Sundry" means consisting of a haphazard assortment of different kinds.
