Lucius Fox (Morgan Freeman)

Lucius Fox was played by Morgan Freeman in Christopher Nolan's Batman Films.
Lucius Fox was a research head and a friend of Dr. Thomas Wayne who was demoted by Wayne Enterprises CEO, William Earle to overseeing the supplies of Wayne Enterprises' aborted research projects and prototypes in the Applied Sciences Division. Upon returning to the business, Bruce Wayne struck up a fast friendship which allowed him to all but recruit Fox as his armorer for Batman's activities. Fox proved invaluable in that role, even when he was fired by Earle. Among other things, he supplied Bruce with the materials that became the Batsuit and the Tumbler. In addition, Fox provided the cure for Scarecrow's Fear Toxin.
