Why so secretive?
Warner Bros. is wrapping production soon on "Joker: Folie à Deux," and still the studio has revealed barely any details about the much-anticipated sequel to 2019's "Joker."
The high-profile project has been making headlines recently as its stars have been spotted shooting the DC film around New York City — prompting fans to speculate online about the characters and the plot, which has been kept tightly under wraps.
