Let's Fan-Cast Folie a Deux's Fictional Joker TV Movie
Briefly

The film includes an in-universe analogue to the 2019 Joker: an unauthorized TV movie about the crimes of Arthur Fleck that everybody has seen and almost nobody likes.
Folie à Deux never shows us this TV movie, perhaps because that would be funny and interesting, two qualities the film abhors.
Tommy Lee Jones was not above playing real-life murderers, and he had the right combination of star power and darkness to convincingly inhabit Arthur Fleck.
Joe convinced me that Chamberlain was a smidge too classy to star in the Joker TV movie, which everyone in Folie à Deux agrees is terrible.
