Here's a clip from the direct-to-DVD animated Green Lantern: Emerald Knights release, which will debut on DVD and Blu-ray on June 7th, just ten days before Martin Campbell's live-action Green Lantern movie opens in theaters.

Nathan Filion (Serenity) provides the voice of Hal Jordan, while Elizabeth Moss (Madmen) voices Arisia Rrab.  Unlike the first Green Lantern animated feature (First Flight), Emerald Knights is an animated anthology of stories based directly on classic Green Lantern tales from the comics--and , judging from reports from Wondercon where the film was screened, it is a major improvement from the first Green Lantern animated feature, though it is somewhat difficult to tell that from this lowkey clip.
