It's important not to get too invested in movie casting rumours. Some people built Doctor Strange in the Multiverse of Madness up to impossible heights in the run up to its release, so much that even several dozen cameos weren't enough to satiate some fans. I'm still not quite over Harry Styles ditching Nosferatu at the last minute to run around as a superhero, leaving Robert Eggers, Anya Taylor-Joy, and of course myself, in vampire remake purgatory. Timothee Chalamet has allegedly joined the project since, but baby, call me Roger Daltrey because I won't get fooled again. I'm trying not to react to the buzz that Saoirse Ronan will team up with Greta Gerwig yet again to play an 'alternative Barbie' opposite Margot Robbie next year. But there is one rumour I cannot help but let get to my head - Lady Gaga as Harley Quinn across from Joaquin Phoenix.
When discussing the Folie a Deux title of the sequel last week, I suggested that Harley (at that stage considered an outsider to be in the movie), was a much more natural pick for whoever Arthur Fleck might share his madness with than anybody else. The established timeline seemed to rule out Batman, another villain like Riddler or Two-Face seemed too Joker Cinematic Universe for Phoenix, and the title seemed too literal for a metaphorical representation of the audience, or of the divide between Fleck and Joker in one body. Harley, more popular now than she has ever been and still significantly less saturated than many other A-list superheroes, always seemed at the front of the queue.
