From IGN: Intro: "Over the course of one of the most brutally hot and humid days imaginable, a select group of press... paid a visit to New Orleans for a behind-the-scenes look at the next big DC Comics movie."
As epic as Star Wars? "Oft-described as DC's answer to Star Wars, everything we saw that day indicated that the Force is strong with this project. The studio's not allowing us to go into too much detail about what we saw....(not yet)..."
What were they shown? "We didn't get to observe any actual filming being done -- they were shooting performance-capture scenes with Ryan Reynolds as Hal Jordan on a nearby sound stage -- but that's fine since the filmmaking team essentially showed us the entire movie (albeit in storyboard form)! Production designer Grant Major showed us around the art department room where we saw set models, cardboard stand-ins of Green Lantern Corps members Kilowog and Tomar-Re (grainy images of which have since leaked online), concept and production design art work, costume and makeup stills, the works.
Inspirations for the story from the storyboard shown to them "The biggest story influence was obviously Johns' "Secret Origin," but it's definitely not a beat for beat retelling of that arc. It deviates from it in several key ways, some good and others we're withholding judgment on until we see the final film."
Which Green Lanterns are in it? "We're prevented from telling you which other Green Lanterns beyond Hal, Sinestro, Tomar-Re and Kilowog are in the film, but let's just say you'll see more of your favorites.... The look of the aliens, while not yet final, were largely faithful to their comic book counterparts."
What about Sinestro's look? "With the exception of scars that now line his face and a slightly shorter haircut along the sides of his head, Sinestro (Mark Strong) looked pretty much exactly like his comic book counterpart."
The Setting: The concept art we were shown -- two pieces of which you can see in this report -- were all stunning, promising a picture that's epic in scope, colorful yet not gaudy.
Costumes: "The costume designs we saw were not final, but they were, like the creature designs, largely faithful to their comic book counterparts sans the white gloves. "
What blew you away? "The biggest lasting impression left by the models of different venues on Oa and all of the conceptual art work was how epic the film is striving to be. The colorfulness of the Lanterns is off-set by the austere starkness of the slightly slate-colored realm of Oa"
