Here's the synopsis if you haven't seen it and need to prime the pump (from Fandango):
Five lifelong friends reunite to complete a historic pub crawl from their youth, and find that reaching the fabled World's End tavern will be no simple undertaking while they also fight for the future of all mankind. Twenty years ago, Gary King (Simon Pegg) and his pals embarked on the ultimate drinking marathon. But the beer got the best of them, and they failed to drink their final pint at the World's End pub. Now, as die-hard rebel Gary approaches middle age, he summons his old friends back to their hometown for another round. With each pint down, Gary and the gang take another step toward reconciling with the past. Yet just when it starts to look like their goal is in sight, the pals realize that a much larger struggle is currently taking place, and that the future seems particularly grim -- not only for them, but for the entire human race.
The movie's got a run time of just under two hours. The Blu-ray edition boasts over three hours of "apocalyptic bonus" footage. That's a rather favorable ratio when considering what you might pay for a movie or at least to own a movie as opposed to rent it. The fact is that some releases see little more than a commentary track and a trailer. Not this one. The commentary track is from Edgar Wright and Simon Pegg who are as informative and funny as anyone who gives a commentary. They care. You can tell that just by listening. The best way to celebrate this end of the Cornetto is by letting these guys send it up and off and let them take their rightful bows.
Completing the Golden Mile: The Making of the World's End is a solid featurette. You'll get intimate with the cast and crew and figure out just how this "trilogy" started and how it came to end. There are a pile of stars in this movie, more so than in the previous installments and each one got involved with World's End in a unique way. Give em a chance to tell their story. You might consider bringing a tissue though because there's a whole lotta heart here.
Now for the Blu-ray exclusives: Storyboard Picture-In-Picture, Trivia Track, Edgar & Simon's Flip Chart, Deleted Scenes and Out-takes, Signs & Omens... it just keeps going and going. As you might expect from a release like this, the out-takes are as funny as anything in the movie. The movie itself looks and sounds really great. Given the year team behind it you shouldn't be surprised at the quality of the release.
Thanks for the memories Simon, Edgar and Nick. We hope you go for a fourth when you're ready. These are the collaborations that make good horror fans.
