For fans of director Edgar Wright and actors Simon Pegg and Nick Frost’s previous work together (Shaun of the Dead, Hot Fuzz, TV’s Spaced), confirmation that the trio’s next film, The World’s End, would begin shooting this September came as splendiferous news.  Not only was a planned production start date announced, but we also got a possible release date (Spring 2013) and a full logline for the plot.  The story involves five childhood friends who reunite when one of them becomes hell bent on trying an epic pub crawl that they all failed to complete 20 years prior.The full synopsis notes a struggle for “the future of humankind,” which hinted that there was more to the story than a standard pub crawl.  Wright and Pegg recently elaborated a bit on the film, with Wright confirming that the pic could be classified as a “sci-fi comedy” or "social science-fiction." Hit the jump for more.Speaking with Empire, Pegg said that the film involves “a crawl through twelve pubs, culminating in the final one, which is The World’s End,” with Wright adding that the pic is “as much about where you grew up as the people you grew up with.”  Though Shaun of the Dead and Hot Fuzz both featured characters in extraordinary situations, Wright and Pegg’s scripts aren’t lacking for earned, heartfelt moments or complex characters.Wright and Pegg tackled the “zombie rom-com” with Shaun of the Dead and action pics with Hot Fuzz, so Empire pressed the scribes for what we can expect from The World’s End:

"Hard to say," says Wright, before deciding. "It's a sci-fi comedy." "Social sci-fi," adds Pegg. "Social science-fiction," agrees Wright, warming to the task. "Look it up on Wikipedia and then bone up on John Christopher and John Wyndham."

As you wish, Mr. Wright.  Here’s the definition for “social science-fiction” per Wikipedia:

Social science fiction is a term used to describe a subgenre of science fiction concerned less with technology and space opera and more with sociological speculation about human society. In other words, it "absorbs and discusses anthropology", and speculates about human behavior and interactions.

Samuel Youd wrote a young adult series titled The Tripods under the pseudonym John Christopher beginning in 1967, which centered on a post-apocalyptic society that had been conquered and enslaved by an alien species.  John Wyndham wrote a post-apocalyptic novel of his own called The Day of the Triffids which also centers on a non-human force destroying civilization.

Is Wright hinting that The World’s End will center around a pub crawl that takes place during an alien invasion of some sort?  I would assume so, but regardless I’m thrilled that Wright, Pegg and Frost are finally reuniting and I’m beyond thrilled to learn that they’ll be dabbling in sci-fi for the closing chapter in their “Blood and Ice Cream Trilogy.”
