Festival-goers have been urged to wear zombie costumes
Filmmakers are hoping to record the largest official gathering of "zombies" at a Herefordshire music festival.
Revellers at the Big Chill in Ledbury have been asked to be extras in I Spit on Your Rave, a collaboration between Warp Films and Film4 on 6 August.
People have been asked to arrive in costume for filming, but make-up will be on hand to get the zombie look.
A festival spokesman said 1,227 people took part in the largest official "zombie walk" in Nottingham in 2008.
Many smeared flour over their faces and wore torn clothes for the event in Market Square, where they did Michael Jackson's Thriller dance.
He added more than 3,300 people took part in a similar event in Michigan, in the US, last year, but there were doubts over whether it was officially recorded.
I Spit on Your Rave is set nine years in the future, with mankind extinct following the release of a deadly virus.
Katrina Larkin, the Big Chill co-founder, said they were looking forward to the filming.
"When Film4 first approached us it took us about a week to stop laughing at various Big Chill zombie scenarios.
"Now the festival draws closer we are relishing the challenge to produce our own zombie movie and bring out our inner zombie."
