"Green Lantern: Emerald Knights" is the 2nd direct-to-video movie showcasing the Emerald Gladiator, and preceded the live-action "Green Lantern" by just a few weeks.
"Emerald Knights" is, at its core, an anthology, collecting short stories from the Tales of the Green Lantern Corps backup feature in Green Lantern back in the early-to-mid-80's, and adapting the original scripts by the likes of Dave Gibbons, Kevin O'Neill, and others into this full-length feature. Hal Jordan (Nathan Filion, Castle) relates most of the stories to one of the newest Lanterns, Arisia, who was, in fact, introduced to comics fans in a miniseries some 30 years ago.
Here's the trailer:
The film's cast also includes singer-actor Henry Rollins (as Kilowog), wrestling icon Roddy Piper, and Kelly Hu ("The Scorpion King"). The film does those short stories justice, and is, to be truthful, a better effort than the live-action movie. Nathan Filion is a lot more convincing as Hal Jordan than Ryan Reynolds was. Then again, that seems to be pretty easy to do.
