Ryan Reynolds and Co. Teach Green Lantern 101 in Behind-the-Scenes Featurette

Newbie Green Lanternites can learn all this and more in WB's new behind-the-scenes featurette for the June 17 superhero flick, while hardcore fans get new glimpses of Parallax doing its thing on an entire city block. There's something for everyone!

I don't know about you, but the more I see of these magical emerald-hued cosmic CG effects, the more into Green Lantern I get. Those racy Blake Lively pics may or may not be legit, but these behind the scenes sneak peeks are real, and they're fabulous.
