Two Just Stop Oil protesters interrupted a play starring Sigourney Weaver — bringing the show to a halt with a confetti cannon. Weaver, 75, was mid-show at the Theatre Royal in London’s West End on Jan. 27 during a performance of “The Tempest” when two members of the environmental activist group climbed on stage, carrying a sign that read, “Over 1.5 degrees is a global shipwreck,” video shared by the group shows.
