Todd Phillips’ version of the Joker endured a fair amount of solitude in his first outing, but Joker: Folie à Deux throws all that out the window. Not only will Arthur Fleck (Joaquin Phoenix) find a kindred spirit in Harley Quinn (Lady Gaga), but he’ll amass an army of supporters as he stands trial for the murder of Murray Franklin (Robert De Niro). His exploits have made him infamous — quite the opposite of his status in 2019’s Joker — and that gives Phillips the freedom to expand his world by adding some familiar characters.
