Welp, you might as well stop editing together footage from Firefly and 28 other movie, television, and video games to piece together a Nathan Fillion-starring fake trailer for Green Lantern, because this guy Jaron Pitts has done it, and you probably aren't going to be able to beat it unless you include several squirrel Green Laterns. This guy has knocked it out of the park and into the internetverse.
The real Green Lantern movie doesn't have a chance against awesome sequences from other movies with green effects digitally inserted:
Well done, sir. You did it.
