On Tuesday night, Entertainment Tonight will premiere the first full trailer for Green Lantern. To hype that episode, they released a thirty second clip showing scenes from the trailer. You can see the CGI costume snap appear on Hal Jordan, quick glimpses of Oa, Kilowog, and even a giant fist from the ring. The trailer is also expected to appear in theaters this weekend with Part 1 of Harry Potter and the Deathly Hallows, so if you’re checking that out you may get to see it on the big screen.
