The actor compared his experience of preparing for the role to how the football stars train for the NFL, explaining, “It’s just having kind of clear goal and setting it.”

It's part of your job, right? It's like you get really routinized about it and kind of build your day around all that stuff. That's kind of the physical side of getting ready.”
