Although Hulk, Thor, and the Avengers introduced humankind to heroes that were not earthbound, "Guardians of the Galaxy" is the first Marvel Studios movie that really turns the superhero paradigm upside down -- or at least takes it to outer space. Featuring a cross-section of unusual characters, including a talking raccoon, who find themselves in possession of an unusual but "highly coveted" object, writer-director James Gunn's film expands the Marvel Cinematic Universe in both literal and metaphorical ways, and Comic-Con International attendees enjoyed an opportunity to see an early look at the film as it wraps its first days of production.

Following a presentation of footage in Hall H, Gunn and cast members Chris Pratt, Zoe Saldana, Dave Bautista, Benicio Del Toro, Michael Rooker, Djimon Hounsou, Lee Pace and Karen Gillan sat down in front of a horde of reporters to talk about their roles and the challenges of bringing this unconventional comic book adaptation to the screen.

What's the basic moral premise and conflict of Guardians of the Galaxy?

James Gunn: Guardians is about a family coming together. It really is about a group of individuals who have acted selfishly and only as individuals, throughout their life. And they learn something about themselves that makes them heroes.

As they expand the Marvel [Cinematic] Universe, will there be a connection between the Guardians and other Marvel movies?

Gunn: Well, we have Thanos. Thanos is the thing that connects us to the Marvel Universe, at this point. In the future, we'll see what happens after that. But right now, we're connected to the rest of the Marvel Universe because of three seconds at the end of The Avengers.

Your previous films have more of an R-rated tone. Are you keeping a darkly comedic tone with this film?

Gunn: I don't think of it as darkly comedic. I do think of it as me, I've gotta say that. There's a lot of James Gunn in this movie, and it's a strange thing. When I turned in the first draft to Kevin [Feige] and Marvel and Joss [Whedon], and they read the first draft, they were all really happy, which made me happy. That was a really good day. And their biggest note was, "More James Gunn," which freaked the hell out of me. So, I gave them more James Gunn, and that's what's in the movie.

I think it's a really unique movie. But with every movie I do, I'm speaking to a certain part of myself and I'm speaking to a certain audience. With a movie like Super, I'm speaking to a specific person that that movie means a lot to. I really appreciate everybody who loves that movie. When I'm doing a movie like Guardians, it really is for a much broader audience. It's for everybody. It's a movie we can go see on a Friday night, with everybody else in the city, and really enjoy ourselves in a different type of way. And I appreciate both of those types of movies.

What has your experience been like on set, with this big budget?

Gunn: That it's easier. With a movie like "Super," there are a lot of people on set who I think, I can do their job better than they can. With a movie like this, we worked really hard to find the best, whether it was the best actor for each of these roles, which we worked really hard at, but also the best production designer, the best composer and the best costume designer. They all make my job a lot easier on this movie than it's been in movies past.

As actors, is it intimidating at all to step into these roles that people might not be as familiar with as they are with some of the other characters in the Marvel Universe?

Zoe Saldana: It's exciting! Of course you're nervous, but I would be cautious to use the word intimidating because I don't want it to be interpreted like I feel inferior. I feel very excited to be joining the Marvel family of superheroes. I do believe that the Guardians have bigger powers, in a way. If we were up against Captain America, or Thor, we'd totally kick his ass.

Chris Pratt: All the Marvel movies, thus far, have been received so well because they were such famous comic books, but I think they were [also] great stories. Iron Man is Iron Man now because of "Iron Man," the movie. It was a comic, and certainly people knew it, but they love [the movie] and they go back to it because it's great storytelling. It's the same thing with this. This is a really cool story. Marvel knows what they're doing and they know how to tell a story and they know how to make this movie. I really don't feel intimidated. If you told me, "Chris, you have to go adapt 'Guardians of the Galaxy' into a movie on your own," I would be super intimidated. But when they're like, "We're doing it and we'd love you to be a part of it," it's like, "Wow, great! I'm along for the ride!"

For the actors, what is your favorite weird and wonderful aspect of your character?

Michael Rooker: There's a lot of me in Yondu. When I first read the script, I noticed right away that there are some aspects of Yondu's existence within this universe of ours that were very, very close to me. For example, the tough love that I have towards some of the other cast members. I'm very much like that in my life, as well. I hardly ever do make-up, in the movies I've done, except on James Gunn movies. This one is about two-and-a-half hours. To me, that's a very interesting aspect. When I get mad, I turn red. When I get embarrassed, I turn red. When I get turned on, I get red. And I want the audience to see that, in the character. So, if the character is getting mad, getting upset or getting turned on, you're getting to see that in the facial tones and the skin tones. That's what I enjoy about acting. It can be very subtle, like that. With a lot of make-up on, you can't see a lot of that, so I prefer to have no make-up, at all. But not in this one. I'm very excited to be involved with this.

Djimon Hounsou: I play Korath, who is a humanoid. I have a 4-year-old son, who loves all the superheroes from Spider-Man to Batman to Iron Man. He's got all the costumes. And one day, he looked at me and said, "Papa, I want to be light-skinned, so I can be Spider-Man, 'cause Spider-Man is light-skinned." That was a shock to me. I'm extremely excited to be a part of the Marvel Universe, so I can provide a diverse outlook of superheroes or bad guys in those stories. It's important for us to be part of that, and specifically for me. That was my in ticket to the Marvel world, and I'm excited.

Lee Pace: I play Ronan the Accuser, a character that's been around since 1967, when he first walked into "Fantastic Four." So, there's a lot of incredible story that I've gotten to research. If you call reading comic books research, I guess I've been doing my job. I start work this week, filming the character, and I'm just really excited to make a villain that is complicated. There's a core to him where you can find something that you can understand. I don't know. He's pretty bad, though. It's the early days, so I'm just putting the first wall up and we'll start there.

Dave Bautista: I play Drax the Destroyer, who is also a pretty bad dude. Drax is full of rage and he's full of honor and he's very literal. I think the best thing about Drax is that he's hysterical without meaning to be.

Saldana: I play Gamora. The weirdest thing about her is that she turns green when she blushes, she turns green when she's mad, and she turns green when she's turned on. And what's wonderful is that she has grown up in an environment that has misrepresented how she truly feels inside and she's gonna discover that, hopefully.

Pratt: For Quill, without blowing too much of his origin, or anything like that, there's a petulance to him. He hasn't really been held accountable, as an adult. He's been able to be free in space and do whatever he's wanted to do. That's really fun because it means that he's slept with all these super weird aliens. That's my favorite weird element of the character. It's just very wonderful.

But, my favorite moment that I've had was when I first donned my full wardrobe in the costume department. I put it on and it was just like, "Wow!" I wore it, and I thought that was pretty wonderful. All of a sudden, my walk changed a little bit, and I had a little extra bob in my head. That was pretty cool.

Karen Gillan: I play Nebula, and she looks pretty weird. One of the most interesting things about the character, for me, is her very strange and complex relationship to Gamora.

Benicio Del Toro: I play The Collector, and he collects things, like I do. I think it's pretty cool that he's got his own personal zoo.

Chris, what was the extent of your training to get your body into the physical shape it is now?

Pratt: Oh, man! It was about six months, and a combination of different things, like lifting weights, cardio and really strict nutrition. It's some really boring stuff. Basically, I cried 40 pounds off, and the rest was being hungry and running a lot.

Has anybody gotten hurt on the film?

Saldana: Well, we still have 85% of the film to shoot, so we could. I think there is going to be a great deal of soreness and muscle cramping and sweating, but it's gonna be great. We've all been training for it and rehearsing, and had endless conversations with our director, as well as talking to every department that's building us together. [Some of us] have so much make-up to do, constantly, with retouching, every single second. There's a lot of work put into it.

I'm just excited to be doing something different. This is sort of like the anti-hero, hero movie. When you meet these characters, they're thieves, they're rebels and they're assassins, but they're gonna be learning very big lessons. Because it's a James Gunn interpretation of "Guardians," the levity will be very abundant, and that's what keeps it awesome. My 10-year-old niece just visited the set, and when we both walked into one of the sets they had built, we both had the same expression and we were both drooling. It was insane!

Dave, how strong is Drax the Destroyer, and can he beat up Hulk and Thor?

Bautista: I would have to say yes, on that.

Saldana: Have you seen his hands? For the love of God! If it's raining, I just tell Dave to put his hand over my head.

Bautista: This part is, by far, the biggest thing I've ever done, in my life. To be a part of this is really a dream come true. I really come from nothing. I'm a poor kid from the streets. What I've been able to achieve has really just been through hard work and not letting anyone tell me that I couldn't do something. I always try to encourage people to just pursue your dreams.

Has your previous experience with WWE and the live shows for RAW helped prepare you for doing film roles?

Bautista: No. Going on auditions, for me, is the worst thing in the world. It's just terrifying. I perform in front of 100,000 people, but this is so much more intimate. There's just so much attention, right there on you, and it's absolutely terrifying. This is new to me. I'm still a student at this. I'm not afraid to let people know, "This is new to me. I'm still learning." I'm not afraid to go up to people and pick their brains and ask for advice. To me, that's how you get better. That's how I've gotten better at everything I've ever done. Don't be too proud to ask for help.

I'm learning a lot, every day, on this film, from the director and from the crew and even from the producers. That's what it's all about for me. To me, that's how you stay young. If you're pursuing something that you love and you're learning something new, every day, that's the key to youth.
