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.

I couldn't find out the full story, but apparently the distributor only made 32 copies for theatrical release. It looks like they decided early on it was 'straight to video.' There were showings around the country. I myself have only seen it on DVD
I saw it at a midnight showing at an art theater. It was a cool place, gentrification killed it and the pandemic finished it off. Anyways, the thing I remember about this movie was how the weirdness obscured the subtext, which is how the main characters, dementia addled elders, face death with dignity. I remember liking it more than I thought I would.
There was a brief period when straight to DVD meant that some really off the wall movies could get made even if they'd never see in theaters.
Here's an oddity that flew in under the radar.
