9. Cillian Murphy - The Scarecrow
In the comics, the character of Jonathan Crane was somewhat of a joke - a gangly, geeky villain with a secret fear of Batman; I never felt that they were making proper use of the awesome concept that was the Scarecrow. The rogue's ghastly redesign in the 1997 fourth series of Batman: The Animated Series (The New Batman Adventures) and the later casting of Cillian Murphy as the villain in 2005's 'Batman Begins' was what helped redefine the character as a sinister, psychopathic, threat. Murphy played the character as a cold-hearted, remorseless, monster who dwells in the very nightmares of his victims - the actor's psychical appearance and reputation for playing sinister villains, helped in creating frightening believability, despite limited screen time. Even though 'Batman Begins' was a tremendous movie, I do feel as though they underused the Scarecrow, who in my opinion, was the most interesting villain in the film.
