For a high-profile movie with an ensemble cast, The Avengers has remained surprisingly secretive, with even the inclusion of the villain Loki uncertain until Marvel officially announced it just yesterday. It's not Dark Knight Rises-secretive, mind you, but the studio has managed to keep a fairly tight lid on leaks.

That is until someone apparently got his hands on a copy of Joss Whedon's script. And not just any copy -- Samuel L. Jackson's copy.

Obsessed With Film revealed today that it was contacted by an anonymous source looking to "negotiate terms" for a 129-page shooting script -- under the production title "Group Hug" -- belonging, at least briefly, to Nick Fury himself. Asked for proof, the source offered up photos of some of the pages, all bearing enormous "SAMUEL L. JACKSON" watermarks and offering a glimpse of dialogue between Black Widow, Iron Man and Bruce Banner in a scene presumably set on the damaged S.H.I.E.L.D. Helicarrier.

The script certainly looks legitimate. But unless Obsessed With Film, or another website, is willing to cough up some cash and then run the Disney legal gauntlet, we probably won't know for sure -- at least until we hear Scarlett Johansson speak the words "Doctor ... Bruce, it's okay, I'll get you out of this."

The Avengers, which opens May 4, 2012, stars Robert Downey Jr., Chris Hemsworth, Chris Evans, Jeremy Renner, Mark Ruffalo, Scarlett Johansson, Clark Gregg, and Samuel L. Jackson, who should probably keep a better eye on his script. It's shooting now in Albuquerque, New Mexico.
