This is excellent: It’s a fake trailer for a nonexistent (but wished-for) GREEN LANTERN movie starring the Serenity and Dr. Horrible actor (and geek fave) Nathan Fillion. YouTube user jaronpitts grabbed footage from a wide range of contemporary and classic science-fiction films, including PLANET OF THE APES, SERENITY, GALAXY QUEST, THE DAY THE EARTH STOOD STILL, and ESCAPE FROM WITCH MOUNTAIN, and then used Adobe After Effects to add various cool effects. The end result is surprisingly cohesive and awesome.
