Hardy is showing himself to be among the most unpredictably diverse actors of today. Next year will see the release of the moody "Locke" and the crime-drama "Animal Rescue," also starring Noomi Rapace and James Gandolfini. And Hardy will also take over for Mel Gibson in the upcoming extension of the Mad Max franchise, "Fury Road."

Directed by Michael Gracey -- also attached to a biopic of P.T. Barnum starring Hugh Jackman -- the film will be written by Lee Hall, whose previous credits include "Billy Elliot" and the adaptation of "War Horse."

John is said to be re-recording some of his biggest hits for the movie, which would seem ready-made for a subsequent adaptation as a stage musical. With John's partner, David Furnish, among the project's producers, "Rocketman" will presumably be a tale more of triumph than tragedy. The film is being made by the recently restructured Focus Features.

Pop piano virtuosos are enjoying something of a vogue in Hollywood. The Hardy/John announcement comes on the heels of Michael Douglas' Emmy-winning turn as Liberace in "Behind the Candelabra." And Sacha Baron Cohen recently departed a biopic project of Queen singer Freddie Mercury, with "Skyfall" actor Ben Whishawrumored to now be up for the role.
