The prank followed the most shocking moment in recent Oscars history on Sunday, when Warren Beatty and Faye Dunaway announced that "La La Land" had won best picture, only to realize they had the wrong envelope and "Moonlight" was the actual winner.

Academy President Cheryl Boone Isaacs has said that Cullinan and fellow PwC accountant Martha Ruiz will not participate in future Oscars ceremonies.
