I know she’s a singer, but her control over her voice is just outstanding. Certainly, the musical element of this film has been one of the many critiqued elements of Joker: Folie à Deux, with only one original song and a myriad of covers with confusing tones and messages.

Make no mistake: Joker: Folie à Deux is an atrociously grim and boring movie.

But a new one has entered the realm of Harley-lore alongside the only other live-action portrayal from Margot Robbie in "Suicide Squad" and "Birds of Prey." In Todd Phillips' "Joker: Folie à Deux," musician Lady Gaga ditches her pop star digs to morph into an unrecognizable version of the character.

Folie à Deux,” Lady Gaga will introduce audiences to Lee Quinzel, her version of the Joker’s love interest Harley Quinn from the DC comic books.

For those who missed the first Joker movie, Folie à Deux has you covered. It opens with a Looney Tunes-inspired animated sequence that somewhat summarizes the first. Arthur Fleck (Joaquin Phoenix) is backstage at his late night show before a shadow attacks him. The shadow takes his costume and performs horrific acts that Arthur gets convicted for.

Joker dancing on the stairs is one of the most memorable scenes from the first Joker, and in Folie à Deux, Lee talks several times about the iconic stairs. Scenes of Gaga dancing on the iconic stairs were also filmed, but were eventually cut from the movie.

The singer, 38, plays Harleen Lee Quinzel – aka Harley Quinn – alongside 49-year-old Joaquin Phoenix’s Joker character in the drama sequel, which critics and fans have mauled – resulting in a taking of under $US40 million ($A59 million) at the domestic box office.
