While Mitte noted it was “hard” to play the part, he explained how he channeled his own past experiences into the role.
“For example, I used to walk on my toes a lot when I was a kid because I could barely move my feet,” he noted, “so when I was learning to portray Walter Jr., my mom would remind me about that. It was a big help.”
