Hardy says the much-talked-about voice he developed for the role was inspired by his desire to honor the comic character's brains and heritage, albeit in an elliptical way. He wanted a sound that conveyed malevolence and old-soul wisdom.
"There were two doors we could walk through. We could play a very straight forward villain or we could go through this very quirky door, which was totally justified by the text but may seem very, very stupid." Not surprisingly, Hardy chose the second option. "It's a risk because we could get laughed at, or it could be very fresh and exciting."
