This is a brag, but I'm proud of it, so I don't care: the Cockneys Vs Zombies script is now in the permanent collection of The Library of the Academy of Motion Picture Arts & Sciences.
If you have access, then you can go to their reading room and, er, read it. Please don't shout out the rude lines, or act out the kills, or try to rally other readers into barricading the library against zombies. I think they'll probably suspend your access for that.
It's my shooting script from April 2011, and it's pretty much exactly what ended up on screen, except for a few trims in the edit, and some random ad-libs. I'm very pleased they requested a copy, and presume that means I'm now completely respectable, or something.
