There is a new film about Orion being made by the talented moviemaker from England, Jeanie Finlay. Here is what the website says:

ORION: The Man Who Would Be King tells the story of Jimmy Ellis – an unknown singer plucked from obscurity and thrust into the spotlight as part of a crazy scheme that had him masquerade as Elvis back from the grave. 

With an outlandish fictional identity torn from the pages of a pulp novel, the backing of the legendary birthplace of rock ‘n’ roll Sun Records and a voice that seemed to be the very twin of Presley’s himself, the scheme – concocted in the months after Presley’s death exploded into a cult success – and the “Elvis is alive” myth began.
