(Cover) - -No story type selected- - Martin Campbell says directing a movie about a "flawed hero" is fun.

The director is best known for helming Bond movies Casino Royale and GoldenEye and is currently promoting his upcoming movie Green Lantern, starring Ryan Reynolds and Blake Lively.

The superhero film, based on the DC Comics character of the same name, follows the story of Hal Jordan, a test pilot for the United States Air Force, who becomes the first ever earthman to be inducted into the intergalactic Green Lantern Corps.

Martin and the writers had fun coming up with the concept of how they were to portray a less-than perfect superhero.

"Hal is not someone who has it from birth to be a superhero. He has to learn certain things. The ring sees a potential in him, a potential perhaps he doesn't see in himself yet. It is there, but potential has to be engaged by circumstance," he explained in an interview with SciFi Now. "When we meet him he's not engaged in circumstance to be the hero he can be and eventually will be, so what's fun about that is that as writers we get to write a flawed hero. There's nothing more boring than a perfect guy, and Hal is anything but that."

Martin wanted to keep Hal as "human" as possible compared to his intergalactic surroundings. The New Zealand filmmaker worked hard at maintaining the earthman's "vulnerability" throughout the course of the film.

"The challenge is just to keep Hal human and make sure to bring the character's human journey to the fore, and humanise all the characters whether human or alien," he said. "Hal Jordan is not invincible he's vulnerable. Green Lanterns do get hurt; they get knocked about. They put themselves at great risk." (C) Cover Media
