Some attendees of the Academy Awards on Sunday night plan to wear red pins calling for a cease-fire in the Israel-Hamas war, a notable exception to an awards season in which many Hollywood stars have been reluctant to draw attention to the conflict.

The pins represent the attendees’ alignment with Artists4Ceasefire, a group of celebrities and members of the entertainment industry who signed an open letter urging President Biden to call for a cease-fire. The nearly 400 signatories include Bradley Cooper and America Ferrera, who are both Oscar nominees this year, as well as Cate Blanchett, Drake, Ben Affleck and Jennifer Lopez.

“The pin symbolizes collective support for an immediate and permanent cease-fire, the release of all of the hostages and for the urgent delivery of humanitarian aid to civilians in Gaza,” Artists4Ceasefire said in a news release. “Compassion must prevail,” the release continued.

The Israel-Hamas war has been a relatively small presence on red carpets since the Golden Globe Awards in January, when stars including the “Succession” actress J. Smith-Cameron wore yellow ribbons to signal solidarity with hostages being held by Hamas.
