Cillian Murphy portrays Dr. Jonathan Crane/Scarecrow in Christopher Nolan's Batman trilogy and is the only villain to appear in all three films. This version of the Scarecrow wears a burlap sack with a built-in rebreather, which doubles as a gas mask in his fear experiments. Murphy explained that the relatively simple mask, as opposed to the full scarecrow costume usually seen in the comics, was done because Murphy "wanted the Scarecrow to avoid the Worzel Gummidge look, because he's not a very physically imposing man—he's more interested in the manipulation of the mind and what that can do."
