Jack White may or may not be playing Elvis Presley in a Jake Kasdan movie, Walk Hard. White's publicist, though, is a bit vague about it:
[They] confirmed that Jack "did take part in this movie", but would not elaborate as to whether or not he actually plays Elvis.
Perhaps the vagueness is understandable - of course, Jack White has been bought up by the Coca-Cola company, while Pepsi is the official drink of Elvis Presley.
The official soft drink of Graceland, by the way, has been approved by the Presley "Licensing Division":
"Charged with the responsibility of protecting and preserving the integrity of Elvis Presley and other related properties."
And nothing says integrity like selling your illustrious corpse to a soft-drink company.
