During MTV News and MySpace's live stream Friday (July 23) to promote "Tron Legacy," MTV's Josh Horowitz asked Hedlund about "On the Road," which also stars "Twilight" leading lady Kristen Stewart. "I've been on ['On the Road'] since the fall of '07, and it's sort of been on my mind since then," Hedlund said.
