The production has been rebooted off-Broadway in New York and actress Molly Ranson plays the bullied schoolgirl, immortalised onscreen by Sissy Spacek in the hit 1976 movie, who is drenched in pigs' blood at her prom.
Ranson and co-star Marin Mazzie, who plays her mentally-ill mother, have been struggling to scrub off the fake blood every night, prompting theatre staff to seek out an alternative.
A representative for the show says, "The production is aware of the problem and is doing everything it can to find a solution. (Director) Rick Sordelet is apparently testing a new (fake blood) formula. No word yet if it washes off, but I hear it does smell like cocoa butter."
