If you found yourself feeling a bit confused after watching the previous two trailers, this latest one should help clarify things a bit for non-comic book geeks.
Think of it as a "Green Lantern for Dummies" kind of guide.
Here we get a very straightforward explanation about the origin of the Green Lantern Corps, what the evil Parallax is and how Ryan Reynolds eventually becomes one of the intergalactic peacekeepers.
So check it out. Unless, of course, you already know it all. In that case, just wait until the real deal hits theaters on June 17.
