As you’d expect from the first film in a potential series, a significant wedge of the plot will revolve around how our hero becomes, well, super. In Green Lantern’s case, this involves a convoluted back-story involving an intergalactic police-force, a super-villain named Legion, and a rather nifty green ring…

A fair bit to get through then, but Campbell makes no bones about the task ahead.

“The origin story of Green Lantern is complex, probably one of the most complex,” said the director, “which makes it a challenge to get it right”. He’s clearly done his research though, referencing comic-book miniseries Emerald Dawn as inspiration for his Lantern.

“(In Emerald Dawn) he’s the hotshot military guy who is slightly fucked up,” said Campbell. “In fact if anybody should not be chosen as Green Lantern, it would have been Hal Jordan.”

But if all this sounds worryingly like a Hulk-esque exposition-fest, Reynolds has been quick to reassure fans that there will be plenty of action too.

“It is (an origin story) to a certain degree, but it’s not a laboured origin story, where the movie begins in the third act,” said the star. “The movie starts when it starts. We find out Hal is the guy fairly early on, and the adventure begins.”
