We mention this guy often, because he does more promotion for Green Lantern: The Animated Series than Cartoon Network. I’m not referring to myself, although that is also true, but none other than GL:TAS producer Giancarlo Volpe. During the Emerald City Comicon weekend he released some thumbnails from the series that provided an interesting and often unseen look at the animation process. This time around he releases some thumbnails for the episode “Into the Abyss”. Check some out below and more at his tumblr.
