Variety reports that Rooney Mara and Jonah Hill have signed on for Gus Van Sant’s Don’t Worry, He Won’t Get Far On Foot, based on the autobiography of subversive quadriplegic cartoonist John Callahan. Mara and Hill join a cast that includes Van Sant’s old collaborator Joaquin Phoenix, to tell the life story of Callahan, a Portland, Oregon resident who turned to cartooning—often focused on making fun of sex, violence, and rampant human cruelty—after being badly injured in an auto accident in his early 20s.
