Don’t Worry, He Won’t Get Far On Foot tells the story of cartoonist, John Callahan, who struggled with alcoholism and was left quadriplegic after a car accident. The film is structured nonlinearly, jumping to events before the crash and after when Callahan was in AA.
It stars Joaquin Phoenix as Callahan, but after hearing this movie was originally a project of Robbin Williams playing the role, I couldn’t help but imagine how his personality would have been a wonderful fit. Callahan’s AA sponsor is played by Jonah Hill, though you likely won’t recognize it’s him until he speaks.
