Some of those Hammer films are very D&D, imo. (Now that's a subjective statement, I realize, Not everyone's concept of "what is D&D" is the same). For me, anyway, some of those flicks just have the atmosphere, the attitude, the style, the flavor.
A fine example: 1974's
Watch the original uncut version. The edited North American version was released as "The Seven Brothers Meet Dracula" and also with the exceedingly verbose title "The Seven Brothers and Their One Sister Meet Dracula" (!).
Most critics boil it down to something like "flawed but enjoyable pastiche." Cornball cheese (saying that respectfully), yeah, but awesome imo.
Here is a link to a pretty good synopsis and review.
Battling a vampire...
(This is that this is the first in an occasional, irregular series of posts about movies, TV, and comic books that might not ordinarily be thought of as D&D, but one way or the other influence my D&D...)
