Elvis: Reel/Real Impact

The numbers vary, but most agree there were more than 200 Elvis Presley impersonators in the world at the time of the King’s death in 1977; the number has grown to over 30,000 at present.
Then there are all the actors who have portrayed Elvis on TV and in the movies, from Kurt Russell to Jonathan Rhys Meyers to David Keith to Don Johnson to Harvey Keitel to Michael Shannon to Val Kilmer as the Elvis apparition who advises Christian Slater’s Clarence in “True Romance.”
Is there need for another movie about the artist, the real person, the myth and the legend that was Elvis Presley?
