INTERVIEW: Infinity War Writers on Making Thanos Properly Use the Infinity Stones

This film brings in the Guardians of the Galaxy characters, who you hadn't worked with them before, and are closely associated with James Gunn, creatively, on screen. What was it like writing those characters for the first time, and nailing those very specific voices?

Markus: It's a lot of fun. They do everything a hero is not supposed to do in a movie. They're incredibly off topic, so they are really fun. We've been doing Cap -- Cap does not say anything that isn't pretty much on point. Rocket will wonder how much he's getting paid. He and Quill are constantly undercutting the gravity of the situation.

Also, I really enjoyed writing for Nebula. I think she's fantastic.

McFeely: You can already imagine Rocket with someone and go, "Oh, I'd like to see that person react." Nebula does the same thing but in a different way. Against somebody funny, she's not going to give them anything. And that, in and of itself, is funny.

Markus: She's like the worst audience for a funny person.

Something I'm curious about, from a speculative standpoint -- in the Marvel movies you've written together, you've covered a huge amount of ground. Different characters, different eras, different types of stories -- given all that, are there still Marvel characters out there you'd like to take on?

Markus: There are characters in the comics... I don't know how you do them.

Such as?

Markus: Literally, no one will ever do this -- I say this, and then it'll be announced -- I think Machine Man is hilarious.

I like Moon Knight, but you have to handle Moon Knight in a very careful way, or he just becomes negative image Batman. But there are certain runs in the comics where you go, "That's crazy."

McFeely: I'd love to see Namor. I don't think they even have the rights to him. But that's a guy with a big upside, I think.

Hate to get ahead of ourselves, but let's talk sequel just a bit. Originally these movies were announced as Part 1 and Part 2, but now that's not the case. Since they were filmed very closely together, do you still see them as two parts of a whole?

McFeely: Nothing changed about the movies. The label changed.

Markus: They are two separate works addressing a similar topic. The reason it was changed is because it seemed to shortchange the second one as "some more." And it's really a very different movie and a different tone and a different approach to things, and it seemed only right to let it live on its own, give it its own name.

McFeely: The reason you haven't heard the second title is because we don't want to talk about the second title, we want to talk about this. Even if at the end of the movie it said, "Avengers will return in blank," you're going to talk about that. I don't want you talking about that. I want you to talk about this. Part 2 is the same idea. "Oh yeah, it's only half the story." This is a whole story.

For both of you, which character surprised you in how much fun you had writing them?

McFeely: Thor. Hemsworth will steal both these movies. That's a bit of a nod to Taika [Waititi] and Eric Pearson who re-toned him, but also we put him on a really nice journey that gets a lot out of him as an actor. So I'm really proud of him.

Markus: I will say Gamora. And particularly, Zoe Saldana acts the shit out of it.
