Thanks to Warner Bros. sending over the EPK (electronic press kit) from Martin Campbell's Green Lantern, you can watch 15 minutes of behind the scenes footage.  If you're trying to stay spoiler free, I urge you not to watch the footage as it's loaded with potential spoilers.  However, if you're curious how Green Lantern was made, the footage is awesome.  I especially enjoyed getting to see Geoffrey Rush and Michael Clarke Duncan do their voice over work as Tomar-Re and Kilowog (which is towards the end) and watching Mark Strong become Sinestro in the makeup chair.  You can also see Ryan Reynolds pretending to fly, tons of stunt work, and plenty of Blake Lively and Peter Sarsgaard.  Again, it's some great footage.  Hit the jump to check it out.  Green Lantern open June 17th.

Here's the official synopsis for Green Lantern:

In a universe as vast as it is mysterious, an elite, powerful force has existed for centuries.  Protectors of peace and justice, they are called the Green Lantern Corps. Warriors sworn to keep intergalactic order, each Green Lantern wears a ring that grants him the ability to create anything his mind can imagine.  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 (Ryan Reynolds).

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’s humanity is one weapon no member of the Corps has ever had, and if—with willpower, determination and the encouragement of fellow pilot and childhood sweetheart Carol Ferris (Blake Lively)—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 save the Earth and all of mankind from certain destruction.
