* AlternativeCharacterInterpretation: Even Elvis himself at one point doubts that he's really Elvis. Then he decides that it doesn't matter one way or the other.
** The director states in the commentary that it was intentionally left so that it works whether or not he and JFK are really who they think they are. He specifically points out one line that could be Elvis and JFK talking about their family lives, or both admitting they are fooling themselves.
** There's also a moment that implies JFK's story is true, and this makes the other characters' stories more plausible by extension.
* CrowningMusicOfAwesome: The soundtrack to this film elevates it another level above what it could have fallen into.
** Oh so much so!

** It helps that the score is by Bryan Tyler, who also provided the music for ''Film/SixStringSamurai'', another (albeit indirectly) Elvis-centric film.
* SugarWiki/HeReallyCanAct: No less a critic than Creator/RogerEbert declared this the best acting Creator/BruceCampbell has ever done.
** At a Q&A session before the film was released, Campbell proudly stated "A 68-year-old fatass Elvis who has cancer on his penis. Let's see Tom Cruise tackle THAT part!"
** Also something as an example for the B-movie genre as a whole: A ridiculous plot, schlocky effects, and gratuitous violence mask a surprisingly deep story with compelling characters.
* WTHCastingAgency: Bruce Campbell as an elderly Elvis. And it ''works''.
** According to the commentary, his agent found it so bizarre he initially threw it out.
