In an interview with EMPIRE (picked up by COVENTRY TELEGRAPH)GREEN LANTERN director Martin Campbell details some of the work his team has ahead as it aims to bring the comic book to life.

"It's daunting," he said. "Just the process, something like 1,300 visual effects shots, it's mind-blowing, quite honestly."

Most of the effects shots work will center around the Green Lantern's power ring, he explained.

"It's energized by a battery on the planet of Oa, which taps into the willpower of everyone in the universe. From that ring you can form constructs. So if you got into a fight, you could form a giant fist. Or a fighter plane."

The Warner Bros. film, which stars Ryan Reynolds, is slated for release on June 17, 2011.
