6. The Mad Hatter - Alice In Wonderland (2010)
Walt Disney PicturesJohnny Depp made the brave decision to step outside of his comfort zone to co-star with Helena Bonham Carter in a Tim Burton movie that required him to wear plenty of makeup and a terrible wig in the director's adaptation of Alice in Wonderland, which capitalized on the post-Avatar 3D boom to gross over a billion dollars at the box office despite not being very good. Depp has always been an actor that has been willing to transform his appearance for his characters, all the way from Edward Scissorhands to Jack Sparrow. His manic portrayal of the character is inspired by the mercury exposure and subsequent poisoning suffered by 19th Century hat-makers, but the combination of pasty makeup and wild orange afro make him look like a crack-den version of Carrot Top.
