Thief is great. Definitely a classic from the early '80s.
Yesterday was Dark of the Sun (1968) & Paul Naschy's Inquisition; DotS is a violent adventure film that involves mercenaries in the Congo & a bunch of diamonds. Pretty violent for the time period (sort of tame now). Turner Classic Movies runs it a couple times a year so it's well worth catching if you dig films like Sorceror, Emperor of the North, or Kelly's Heroes.
P.N.'s film goes well with Mark of the Devil but it's not as graphic plus The Devils but it's not as good. There's some nice Satanic imagery, some torture, nudity, The Devil, rituals, etc. Released by Mondo Macabro in the U.S. on Blu-ray. M.M. has another Naschy film in the pipeline & Scream Factory has Vol. 2 box set coming soon including The Hunchback of the Morgue, which, is my favorite. Now, if a label would release Howl of the Devil!
Since Tobe Hooper dropped dead, I've got Salem's Lot playing on this rainy Sunday afternoon...
