[With] this show [This Is Us], I don't think I was seeking something outside of the world I'd always played in so much as I'm ruled by characters. If it's a great character, I'm invested. It doesn't matter what the genre, what the storyline, anything.

How can you sustain life? [Dan] Fogelman is magic, and I think the other scripts of his that I've read for this show specifically are as beautiful as the pilot script [of This Is Us]. And he said it in a meeting [regarding the stillbirth of a child], "You can't kill a baby every week." But I think the idea that you can have these impactful moments that are as heightened as the loss of a child - it's life.

Think about the physical act of pulling a trigger. The amount of pressure it takes to pull a trigger or the speed it takes to shove a sharp object into somebody. The psychology behind it. Why people kill? Why people don't kill?

For me, what grabs my attention about the project is usually the character immediately and then the story, and then the people that are involved.

I learned that I'm not young enough to think I know everything. Honestly. I think you hit a certain point in life where you expect that you have so much to learn, and you may think that you've arrived, but you have kind of just begun.

You have to be able to sustain life. So moments are going to be lighter, but moments are also going to be heavier. I think just the understanding that life goes in a million different directions, and hopefully, if you find excitement by what these characters are experiencing and what they're living through, and you're impacted by them as human beings, then that's the sustainability of the show [This is Us].

I think there's an initial shedding of the skin of a character when you've played them for so long, almost like a snake losing its skin. But when a job is done, I kind of walk away from it because I know that I need to prep for whatever else I'm going onto - I need to get back to being myself, which... Who knows exactly who that is, with all the talking voices in my head. You know, back to being a bit of a blank slate again. It becomes a necessity as an actor - at least for the way that I act.
