America's sweetheart veteran actor Tom Hanks says he is set to play a "bad guy" in the Elvis Presley biopic and he hopes to prove the naysayers wrong that he can only play the good guy.

The actor, who was feted with the Cecille B DeMille award at the recently concluded Golden Globes ceremony, is playing Presley's shifty talent manager Colonel Tom Parker in Baz Luhrmann's untitled biopic on the legendary musician. Newcomer Austin Butler is playing Presley.
