Oh, those clever web developers and their cryptic ways…
If you go to the Green Lantern movie site, right-click on the page, and view the source code, look out for this hidden message:
“GREEN LANTERN – In a universe as vast as it is mysterious, a small but powerful force has existed for centuries. Protectors of peace and justice, they are called the Green Lantern Corps. A brotherhood of warriors sworn to keep intergalactic order, each Green Lantern wears a ring that grants him superpowers. But when a new enemy called Parallax threatens to destroy the balance of power in the Universe, their fate and the fate of Earth lie in the hands of their newest recruit, the first human ever selected: Hal Jordan.”
This is as good as any info we’ve received on the movie since San Diego, so enjoy it while you can.
