Jack’s best friend and a dedicated newsie with a “bum leg” from polio that causes pain, but helps sell more papes. Walking with the assistance of a crutch doesn’t define the ever-positive newsie, so look for an actor who can portray Casey’s goofy-sweet sense of humor and optimistic resilience. Crutchie is accustomed to modifying daily activities for their disability, so consider both the character and actor’s abilities when blocking and choreographing.
