Spoiler leaks for the plot of the upcoming Justice League of America film have been posted by UnderGroundOnline and have been verified by IESB . The team-up movie would include Batman, Superman, The Flash, Aquaman, Wonder Woman, Martian Manhunter and the Green Lantern.

Here are some of the spoilers revealed:

*) Story elements from the screenplay have been adapted directly from DC's JLA comic book series.

*) The Flash is the youngest member of the JLA. He has a crush on Wonder Woman.

*) Wonder Woman is portrayed as the member that acts as defacto humanitarian and face for the League. Our source told us that the best way to describe how she is written in the script is to "think of Angelina Jolie and her relations with foreign countries."

*) Unbeknownst to the League Batman has a piece of technology that he developed called the "Redeye", a cool piece of hardware that he can use to spy unbeknownst on the other League members. Want to know what the secret identity of Superman is? Not a problem. Want to find out what can cripple or kill each League member, their Achilles heel? It's a snap with the Redeye. Batman files away the knowledge in case the day might ever come when he will need to use it to take down a member of the JLA that goes rogue or becomes a villain.

*) The Redeye is a fulcrum to the events that transpire in the movie. A villain ... and I'm not at liberty to say which specific one or ones-will gain control of the Redeye. Instead of serving as a means of protecting the planet's populace from the threat of a superhuman out of control, this creation of Batman's will come back to haunt him, threaten the lives of the League and the safety of everyone on the entire planet.

-- During the course of the movie the day that Batman feared would come happens: a member of the League will, and we directly quote our source here, "go bad."

Justice League of America is scheduled to arrive in theatres in 2010.
