The new DC superhero movie “Birds of Prey and the Fantabulous Emancipation of One Harley Quinn,” which highlights Quinn’s romantic split from supreme villain the Joker, offers an easy-to-miss glimpse into Quinn’s political affiliation.

In one scene, Quinn (played by Margot Robbie) is being held by a new villain named Roman Sionis (Ewan McGregor). The quick-tongued heroine starts rattling off a list of ways she could have offended the bad guy, and for a split-second, one option appears on screen: “Voted for Bernie.”

Director Cathy Yan told The Washington Post that credit for the momentary endorsement goes to screenwriter Christina Hodson, adding it is only meant for humor.

“We always knew we wanted to have this string-out of ridiculous things that Roman would get upset at Harley for, so we just kept throwing things out there,” Yan said.

The quick flash of the presidential candidate’s name is what makes the moment “even funnier,” Yan told the outlet.

“There are details like that throughout the film that on first or even second viewing, you say: ‘Did I just see that?’” she added.
