I think that the idea of boundaries is being challenged everywhere. And I think our fascination with sci-fi is that it is a boundary-less world where we can kind of create the reality that we believe to be as opposed to the reality that is. It is about the beyond and the unknown in a different way than pretty much any type of storytelling is.

It's amazing how the world has changed because, at that time [2005], a lot of actors didn't want to play a gay role.

What world am I living in?' Aren't movies made to have something to say? Why make a movie if you don't have something to say? What are you doing it for? Are you doing it because you want to make a lot of money?

I think, when someone say, "When did you feel like an actor?" it's those moments when I feel like, "I'm an actor, wow." That's an extraordinary moment for me. So it's not like I walk around going, "I'm an actor."

The amount of preparation I saw from someone like [David] Fincher, and how aware he is of everybody else's job on the set, and how much respect he has for every aspect of the film, and every aspect of the frame - that's the type of actor I am now; it's not the type of actor I was then. But without understanding his process, and then coming to learn it later on, I would never be the actor I am now.

One of the things that I'm so proud of [about] that movie [Brokeback Mountain], was to see, within the past basically 10 years, how much has changed. When the Supreme Court [issued a ruling] just a little while ago, I felt like we had been part, a little part and parcel of that movement.

Hardest emotion? They're all pretty damn hard; I don't know really if there's one specifically, but I do think, I don't know what's happening or what I'm feeling when I'm actually listening.
