One of the most ironic aspects in Joker: Folie a Deux is the fact that there is constant mention of an in-movie Joker film based on Arthur Fleck’s life. But although we never see this fake movie, director and co-writer Todd Phillips says they almost did film some of it, and it was supposed to star Beetlejuice 2 actor Justin Theroux.
"Well, Justin Theroux of course," said Phillips in an interview with IGN when asked who plays Joker in the TV film. Fans of the franchise will know that Theroux made a cameo in the first Joker film as actor Ethan Chase who is a guest star on Murray Franklin’s talk show, the same talk show host who Fleck murders at the end of the movie.
"In fact, I talked to Justin about it. We were going to shoot a trailer at one point. We just ran out of time," confirmed Phillips. However, despite it being brought up numerous times, even in the courtroom, the audience never gets a peek at the fake film and Theroux does not appear in Joker 2.
The fake movie becomes a running joke in the movie based on its quality, many people say it's awful yet Lady Gaga’s Harleen Quinzel is a super fan who has seen it 20-plus times. However, it seems as though this is yet another lie she is telling Fleck, who seems to believe her delusions either way.
