A new Green Lantern TV spot aired and was recorded by CBM user albieg25.
Though the spot features mostly footage we've already seen in the Wondercon trailer, there are a couple of new lines from Sinestro addressing Hal.
Check it out below: Updated with High quality.
UPDATE: Now in better "def"
Hal Jordan is a gifted and cocky test pilot, but the Green Lanterns have little respect for humans, who have never harnessed the infinite powers of the ring before. But Hal is clearly the missing piece to the puzzle, and along with his determination and willpower, he has one thing no member of the Corps has ever had: humanity. With the encouragement of fellow pilot and childhood sweetheart Carol Ferris, if Hal can quickly master his new powers and find the courage to overcome his fears, he may prove to be not only the key to defeating Parallax...he will become the greatest Green Lantern of all.
Green Lantern hits theaters June 17.
