The Big Chill festival has teamed up with Film 4, Danny Boyle and Warp films in an attempt to claim the Guinness World Record on August 5th, 6th, 7th and 8th 2010.
As an added incentive, the frighteningly-attired participants will be filmed for a short movie about the event.
Danny should be an expert in zombie costumes having directed the 2002 film 28 Days Later, which was full of them!
The record attempt is also sure to add even more fun to the Big Chill, which is a great summer party.
Elsewhere, at Camp Bestival in Dorset, Alice in Wonderland fancy dress is sure to be the uniform of choice when the organisers attempt the largest ever Mad Hatter's Tea Party.
This will take place on July 30th and 31st and August 1st 2010 should you wish to join in.
