Ok so this is for a friend and these are the only details I’ve been given:
There’s a scene in it where a bunch of Elvis fans are on top of a roof yelling “Elvis! Elvis! Elvis!” To the sky.
She also said it’s a bit of an old movie… not sure exactly how old she means though
Wild guess because I don’t remember that. Honeymoon in Vegas because the climax is the Flying Elvises.
There was a brief scene like that in “Independence Day”, but it was only one of those people who mentioned Elvis.
