Keith Richards, for goodness sake.

He's become so identified with "quirky" roles that it's now a cliché, especially when audiences see he's in yet another Tim Burton film. Case in point: he told the LA Times in 2009 that his usual prep in finding a character includes painting a watercolor "to help him find the face and personality."

In honor of his growing list of idiosyncratic characters, we've ranked his performances from least eccentric to the most wigged-out, behatted, and over-the-top of his career.
