Politics can be a real horror show. Marketing efforts for Jigsaw, the latest installment of the Saw film franchise, include an online campaign that encourages people to donate blood but also criticizes U.S. regulations requiring men who have sex with men to be celibate for a year before donating.

Titled “All Types Welcome,” the ad campaign stars eight social media stars with large LGBT followings, reports The New York Times. The celebrities—including transgender icon Amanda Lepore and New York nightlife luminary Susanne Bartsch—appear dressed as Saw nurses (characters who don’t appear in the movie) and were shot by photographer Tim Palen, who is also the chief brand officer at Lionsgate, the studio releasing Jigsaw.

The Jigsaw Halloween Blood Drive starts October 5 in New York before extending to 25 other cities. The film is released October 27; for more information visit JigsawSaves.com, which, according to the Times, will also provide details on the blood drive.

Previous Saw movies also promoted blood drives. They were so successful that the American Red Cross gave Palen an award. But this is the first year the campaign took aim at the discriminatory regulations.

“We want this policy changed,” Mark Burg, producer of the Saw series, told the Times.

The Red Cross has also been criticized for requiring transgender people to register at blood centers under the gender they were assigned at birth.
