Never afraid to put his all into a role, the actor totally transforms to play the Mad Hatter in Tim Burton's Alice In Wonderland. "This character is off his rocker. He is so much fun and so nutty, I can't imagine anyone else doing it," said producer Richard Zanuck.
Johnny's extreme look is typical of the US filmmaker's style, which in this movie involves clashing colours and mock Victorian fashions.
The features of the star and his colleagues, Helena Bonham-Carter – playing the Red Queen - and Anne Hathaway, the flick's White Queen, have also been digitally altered.
In the adaptation of the Lewis Carroll tale, Alice struggles to fit into Victorian society and is about to be proposed to in front of hundreds of people at a garden party.
As she flees the party, she spots the White Rabbit, portrayed by Michael Sheen, and follows him down a hole and into Wonderland. The inhabitants are waiting for Alice to lead them in a revolt against the wicked Red Queen, who has deposed their rightful leader, the White Queen.
When the film comes out in 2010, the profile of British schoolgirl actress Eleanor Tomlinson will surely rise. Earlier this year the teenager – who plays a catty rival to Alice - revealed to hellomagazine.com how she screamed with excitement on learning she'd be sharing the screen with Johnny and his illustrious castmates.
