THE KING VS. THE KING OF THE DEAD
An aging Elvis Presley and an African-American "JFK" stay in a nursing home where nothing much happens - that is, until a wayward Egyptian mummy comes and sucks out the old people's souls thru their a-holes. The two decide to fight back.
The little touches are what sold me on this movie, like Elvis comparing the scarabs to the “size of a peanut butter and banana sandwich.”
