The highly-anticipated DC comic book adaptation Green Lantern is currently in post-production, and there is already talk of Green Lantern 2. Newsarama recently spoke with Green Lantern writer Marc Guggenheim about the planned sequel, and the rumors that a third Green Lantern movie is already in development. Here is what Marc Guggenheim had to say:

"I think where that came out of was, when Greg Berlanti originally pitched the movie to Warner Bros., he pitched three movies. So there's always been, and he's said this publicly, that there's always been enough story for a trilogy. The scope of the character and the character's world requires that. But we're really just focusing on the treatment for Green Lantern 2."

We reported back in June that Marc Guggenheim, Greg Berlanti and Michael Green were hired to write the treatments for both Green Lantern 2 and The Flash. Marc Guggenheim revealed to the site that their treatment for The Flash was recently completed, although they haven't started work on the actual script yet:

"I think it's very hard to talk about these characters in a closed-ended, sort of non-sequel way, especially characters like The Flash and Green Lantern, which have such rich, long histories. You can't help but talk about the characters and go, 'Oh, I really want to do the movie where we get to this moment, or that moment.' So you're always talking in terms of sequels, but no, nothing's planned. We haven't even written the script yet for The Flash. It's very much one step at a time for The Flash.

Marc Guggenheim also talked about his visit to the Green Lantern set in New Orleans:

"I went down to New Orleans two months ago to see some of the Green Lantern filming, and I got to see a whole bunch of things in connection with the movie. In all honesty, I was completely blown away. I don't think it dawned on me how huge this movie would be until I went down to New Orleans and really saw everything that I saw. It was incredibly eye-opening. I was really rendered speechless. There's just no way for me to put it to words, just how huge this movie is going to be."
