Trivia: When Pietro says he'll help the twins maximise their candy acquisition, one twin says "Kick-ass!" and Wanda repeats to herself "kick-ass." Both Aaron Taylor-Johnson, who played Pietro in Avengers: Age of Ultron, and Evan Peters, who plays "Pietro" in WandaVision and the recent X-Men films, both starred in Kick-Ass.
