GREEN LANTERN - Trailer

I am sooo going to see this!  I for one think this casting is perfect and as an added bunus to Ryan we also get Blake Lively.

For those of you who aren't Green Lantern fans - here is the back story...
There have been many incarnations of D.C. Comic's Green Lantern over the years but the in the late 1950s they revived the Green Lantern character, this time as test pilot Hal Jordan, who became a founding member of the Justice League of America.  This is the Green Lantern that the film deals with.

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.

Hal 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 (Blake Lively), 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.
