From this site;

Apparently some Twilight fans just can’t wait until this summer when the third installment of the vampire series hits screens. According to co-star Jackson Rathbone, a leaked copy of the script has been making its rounds on the internet. Dun, dun, dun! Rathbone knows about the digital script floating in cyberspace because the document in question belongs to him.

The Eclipse script that was leaked onto the net has the watermark of Rathbone all over it, but that hasn’t stopped thousands of teenage girls from taking a peek. The validity of the script is being called into question because Rathbone recently made a few statements insinuating that the released copy doesn’t tell the reader that much about the movie’s plot. Some think it might be a “blue copy,” which is an earlier draft of the final script.

Even though it’s a convenient cover story, some insiders think Rathbone’s statements are a means to cover his tracks. Summit Entertainment might be coming down hard on the young actor for his negligence, and this could be his attempt to negate the interest of potential readers. There hasn’t been any confirmation or denial from the studio regarding the legitimacy of the digital copy, so who knows if you’re getting the real deal.

From an outsider’s perspective, the books don’t sound that great and the movies are even worse, so what’s the appeal again?

Eclipse completed shooting back in October and is scheduled to hit theaters on June 30, 2010.

I personally don't read scripts when they leak and I try to avoid spoiler footage when they release it - hate ruining it for myself!! But how awful is this! Poor Jackson - I hope he doesnt get into trouble...!!

Will you read it if you find it?
