If you’re familiar with the work of Simon Pegg, Nick Frost and Edgar Wright (“Shaun of the Dead,” “Hot Fuzz”), you can jump right in and enjoy “The World’s End” without any doubts as to its pedigree. If you’re new to the trio, you may have to sit back and be patient as the outrageous comedy unfolds and builds up to a delightful level of absurdity that is just out of this world (literally). The premise: Simon Pegg stars as Gary King, an alcoholic loser who never outgrew his adolescence, who cons his estranged four middle-aged friends to relive a night 20 years earlier in which they undertook — and failed — at an epic pub crawl through 12 bars. He literally Shanghais his friends back to their home town for the undertaking — a mile-long trek that’s to end at a pub called The World’s End — but once the quest begins, they find there’s something very wrong in Newton Haven — the town has been taken over by beings from another world. There’s plenty of bathroom and scatological humor, drunken dirty jokes, nasty repartee, and very, very, very funny sequences you just aren’t ready for. A masterful stroke of British humor that everyone can (and should) enjoy. This is the third and final film in the trio’s “The Ultimate Three Flavors Cornetto Trilogy,” which includes the aforementioned hits “Shaun of the Dead” and “Hot Fuzz,” and which is being released to Blu-ray this week.
