Beginning

In the beginning, when the thief opens the Baron's tomb to take what is in his hands, why is the setting a livingroom? Why is it not in a mausoleum?

I can see that some family members might feel they want to visit him in a more comfortable place, but one can hardly sit by the fire on a cold winter day, reading a book, working a jigsaw, or playing cards with him lying there.

I do understand the idea of a parody, and after watching the original Universal Frankenstein, I love the elements it is respectfully making fun of, but perhaps I am missing one of them, if the livingroom is supposed to be an instance of parody.

If it's not just an interestingly strange tidbit, then could someone please explain what part of the original movie it is spoofing. Thank you.
