Not a Hammer Film, I know, but have put it on the Hammer boards as this was Christopher Lee's attempt to "get it right" and be faithful to Stoker.
It also seems to me that the film would likely not exist - and Lee would certainly not be in it - were it not for the earlier Dracula Hammer films.
Have never watched the film properly to date, but my preconceptions of it are that the director was a bit rubbish (while thinking he was a genius) and also overly fond of the zoom lens, so that while Christopher was being brilliant and giving it his all, the production around him was far too busy being shoddy to notice such things.
I feel sorry for Christopher as this was clearly a sincere personal attempt, but I think he was let down badly by amateurish others around him.
