It's rare that audiences ever get a chance to read a movie's screenplay for free, let alone one that's filled with behind-the-scenes secrets, original storyboards, and other little tidbits from the set. But thanks to the guys at Focus Features, we've got our hands on some pretty awesome stuff from the creators of 2004's "Shaun of the Dead".

Simon Pegg, Nick Frost, director Edgar Wright and producer Nira Park — the masterminds behind "Shaun of the Dead" and "Hot Fuzz" — have teamed up once again for this summer's "The World's End", which follows a group of friends who go on a pub crawl amidst an alien invasion. (Naturally.) The film is the third and final installment of the "Three Flavours Cornetto Trilogy" (which also includes "Shaun of the Dead" and "Hot Fuzz", of course).

In support of "The World's End" premiere later this month, the hilarious filmmakers have just released an annotated, interactive screenplay from "Shaun of the Dead", which features never-before-seen photos, illustrations, anecdotes and other cool stuff from the film. Thanks to the power of the internet, the screenplay (which Wright and Pegg started writing back in 2001) is now available for you to explore for free, all from the comfort of your own computer screen. You can even download it as a PDF!

Click, swipe and watch everything you missed from this cult classic the first time around, and check out "The World's End" in theaters Aug. 23.

(P.S. Be sure to keep an eye out for the "Hot Fuzz" screenplay, which is also rumored to be getting the interactive treatment sometime soon.)
