SANTA MONICA, California — He's smart, he's sexy, he's charismatic — and if Cam Gigandet's recent film output is any indication, there's a rosy future waiting for the other "Twilight" saga stars once they're done filming sequels.

Now, Twilighters jonesing for their Gigandet fix can get another dose this weekend, when Cam goes into outer space alongside Dennis Quaid and Ben Foster in "Pandorum." On Monday, he swung by the MTV News studios to discuss the sci-fi psychological thriller, space madness, and why it might have monsters but is no monster movie.

MTV: Cam, the title of the movie comes from a condition that afflicts astronauts sometimes. So what exactly is pandorum?

Cam Gigandet: It's basically a deep-space syndrome that people get, a type of psychosis. There's all sorts of symptoms, whether it's paranoia, you're seeing things, hallucinating, dreaming up all sorts of weird scenarios. It's something that, when you have it, you aren't aware that you have it.

MTV: So right off the bat, "Pandorum" explains to us that what we're seeing through the eyes of yourself and your fellow astronauts isn't necessarily trustworthy? It could all just be their insane ramblings? That's very unique.

Gigandet: Yeah, and they all have no memories. This crew, this capsule or sleeping pod that they're in ... when you're in there for long enough and it preserves your life, you end up losing your memory. While they're trying to figure out all this stuff, they don't know what happened in the past, where they've been, what they've done. Any of that stuff. So you're always suspicious of everyone ... that's one of the cool things about this movie. They're always suspicious, and slowly their memory starts coming back. It's like this puzzle that they put together.

MTV: It's a sci-fi film. It's certainly a thriller. But would you call "Pandorum" a monster movie?

Gigandet: No. But there are monsters. [Laughs.] There's so much more going on; that's just one element of the story. Basically, it's a mind movie. Why there are monsters is more interesting than the monsters themselves.

MTV: Dennis Quaid has been a star for a long time, but his most iconic role was probably in "The Right Stuff." Was it daunting working opposite him as he put on a spacesuit once again?

Gigandet: It was just daunting playing opposite Dennis Quaid as Dennis Quaid. He's a legend, he's so experienced. And the first couple days, I was just trying to act like I knew what I was doing — he quickly caught on. He makes it so easy; he's such a sweet man. His family was there, and he's a quirky guy. I love him.

MTV: Quirky how?

Gigandet: He likes to sing. He likes to play around. He likes to joke and have fun. He's an interesting guy. ... Even towards the end of the movie, I'm always so nervous around anyone [that famous].

MTV: But I would think the nervousness would help you portray your on-the-edge character.

Gigandet: Oh, yeah, of course, of course. I slid right into that.
