15 Years of Mindnumbing Need to Know a Christopher Lee Title...

(Calgary)

What is the name of the movie with Christopher Lee where some teens took his dead body from his tomb and took him to a house and sat him at the dinner table with them and later a guy picked him up and started dancing with him?

The movie also has a casket later on floating in the air and coming down some stairs.

Could you tell me the name of this movie?
