But do you really see the Universal monsters and the Hammer monsters as related? If so, I think you are the first.
I'm talking about the idea of a serious Dracula film or a serious Mummy film that so many seem to think A&C ruined.

But if you want to pin it down specifically on studio continuity, if Universal decided to make a serious Mummy movie in 1955 instead of an A&C spoof, would they really be going back ten years to pick up the continuity of where they left off with the Kharis character? Most likely, they'd do what they did the last time they left a character that long (1932 to 1940) and simply start over.
