A couple of new pieces of information have come to light since the Inside Film story broke a few days ago about the Green Lantern production moving to Mexico. Comments from both Ryan Reynolds and Martin Campbell imply that New Orleans will be the site of the production once filming begins in April, 2010.

Reynolds appeared on Late Night with Jimmy Fallon the other day and the subject of the Green Lantern film was brought up. Besides setting Jimmy straight on the GL mythos, Reynolds said that filming was four to five months away. “It’s crazy, it’s the only job I’ve ever had that I’m not allowed to really talk about. I think there’s like a representative from Warner Brothers who I’m sure is following me around ready to blow-dart me if I say a single word,” joked Reynolds, “I probably have a chip in me somewhere, like if I start talking about it, I’ll just pass away.”

Reynolds is apparently wither getting up to snuff on the GL mythos or is already familiar with some of it. Geoff Johns re-tweeted this from someone behind the scenes on Fallon’s show on his twitter feed:

“I owe him a slurpee. RT @shoemaker @GeoffJohns0 I just went in Ryan Reynolds dressing and tested him on the GL oath. He nailed it!”

Incidentally, Ryan Reynolds is hosting Saturday Night Live this evening on NBC.

Meanwhile, over in the most recent issue of Empire, director Martin Campbell talks about the upcoming film, saying, “It’s daunting. Just the process, something like 1,300 visual effects shots, is mind-blowing, quite honestly.” The article also says that production is being moved to New Orleans and that filming will start in April.

That’s contrary to the Inside Film information, and the Empire article could have been written before Mexico entered into the picture. Either way, it looks like filming is going to start soon so we will hopefully get more casting news in the coming weeks.
