Warner Home Video has released the trailer for their upcoming DC Universe original animated movie Green Lantern: Emerald Knights, which features the voice of Nathan Fillion as Hal Jordan.

Watch the trailer here below. Above is a new image from the film.

As with Batman: Gotham Knights, the new Green Lantern feature will contain six interlocking stories. The stories, which were penned by some of today’s greatest comic book writers — Geoff Johns, Dave Gibbons, Peter J. Tomasi, Eddie Berganza, Alan Burnett, Todd Casey and Michael Green & Marc Guggenheim — center around the Green Lantern Corps and preparations for an attack on an ancient enemy.

Green Lantern: Emerald Knights will be released direct-to-DVD on June 7, just before the June 17 theatrical release of the Warner Bros. live-action film, Green Lantern, starring Ryan Reynolds.

Green Lantern fans have a lot to be happy about right now. Last year saw the release of Green Lantern: First Flight — an animated retelling of Hal Jordan’s first days as a Green Lantern; Blackest Night and the Green Lantern comics are on fire; there’s an upcoming 3D live-action film starring Ryan Reynolds currently filming, and now it looks like there may be another Green Lantern animated film in the works.

Comics Continuum is reporting that Warner Brothers Animation is making another Green Lantern direct-to-DVD animated film that will center around the origins of the Green Lantern Corps, along with the very first ring wielders. Although Warner Brothers has not yet given any type of official confirmation, I suspect it’s only a matter of time before they do.

At the Emerald City Comic-Con last weekend, DC Comics’ Geoff Johns hinted at a Green Lantern animated series, though its unclear whether this is the one he was referring to.
