You gotta see this... - Bubba Ho-Tep

Did you ever think you'd live to find a film with a basic plot of an old aged Elvis Presley teaming up with a similarly aged black man who insists he's JFK to fight off an Egyptian Mummy that's come back to life and terrorising an old folks home? No me neither, but I'm so glad I did.

The film boasts the combined talents of Phantasm director Don Coscarelli, author and star of the Evil Dead series Bruce Campbell (as Elvis) and Ossie Davis (as JFK), and is based on a novella by Joe R.Lansdale. While the film is a wonderful mix of comedy and horror, the film ends up being a touching film about people dealing with growing old and all the problems that entails, loss of dignity, independence and being left alone to die.

This scene explains how Elvis is still alive to fight off the Mummy and ends up in the old folks home and not dying on a toilet and really should be enough to get you intrigued:
