Michael Trevino on tonight’s transformation: “I’ve never been more challenged as an actor.”

JH: So, Michael, the change is coming this week. How freaked out are we all going to be?

Michael Trevino: I just did a looping session yesterday and so I saw a cut with some special effects and it’s intense. It doesn’t happen quick. It doesn’t happen in an instant. It’s very long and it’s a very, very painful process and it lasts the entire episode so that’s what’s going to happen. We shot it over two days and I’ve never been more challenged as an actor.
