In a recent interview, Lady Gaga discussed her transformation for the role of Harley Quinn in the upcoming film Joker: Folie à Deux. She explained that she altered her singing style to reflect the character's lack of formal training, stating, 'I’m playing a character... so I worked a lot on the way that I sang to come from Lee.' Gaga emphasized the importance of removing the technicality of her trained voice to embody Lee authentically, admitting there are 'plenty of bum notes' in her performance. The film, directed by Todd Phillips, will showcase a musical narrative where Joker meets Lee while incarcerated, leading to a tumultuous romance. Gaga's portrayal aims to bring a unique interpretation to Harley Quinn, drawing inspiration from unconventional sources like Charles Manson's followers. The film follows the success of the 2019 Joker, which earned over $1 billion at the box office.
