The one I have seen the most is a Spanish language version of "La Marca Del Hombre Lobo". I purchased a VHS dupe of the film which I purchased from a catalog that use to be connected with the Mark of Naschy website called Euroshades way back in fall 2001. I still own the tape after all this time. Despite not knowing very much of the Spanish language, the visuals make the plot easy to follow, expect for a plot hole in the climax where the vampire villain Dr. Mikhelov (I think that was the character's name) abruptly dies without any explanation. I wish this particular version of the film (with English subtitles) would get a R1 DVD release someday.
