The promotion is inspired by both Valentine’s Day and the new movie “Birds of Prey (And the Fantabulous Emancipation of One Harley Quinn)," the film being the latest in the DC Extended Universe cinematic series. The connection? Well, the film stars Margot Robbie as the character of Harley Quinn, who is apparently dealing with the aftermath of breaking up with the Joker.

Pictures and their new film 'Birds of Prey (And the Fantabulous Emancipation of One Harley Quinn),' Burger King restaurants are celebrating Anti-Valentine’s Day in true Harley Quinn fashion."
