Julia Butters and Margot Robbie's scenes are callbacks to their recent films. Butter's character in Once Upon a Time... in Hollywood (2019) said after being thrown to the floor in a scene, "I got pads on" and she repeats the line here after being knocked down and before punching Angela Meryl. In this video, Margot Robbie clobbers the next fighter with a baseball bat with 'Good Night' engraved on its barrel as her character, Harley Quinn, does to just about everybody in Birds of Prey (2020).
