Lady Gaga

It’s not the choice I would make for her, but she is the only person I can think of whose charisma is big enough to make it work opposite Joaquin.
I'm not familiar with the model for soundtrack albums, but won't the movie production also foot the bill when it comes to recording, thus minimizing her risk?
Sometimes I remember when Gaga's store emailed about this planned £100 bundle and then never released it. 2011 me used to check her store every day waiting to see if it was available to buy.
I feel like Joker was taken a little too seriously by some people? I only just watched it in like October, so I don't know what the conversation surrounding the movie was but I really enjoyed it as a study of the Joker. It was an interesting take on the world of Gotham and the character, but I wasn't expecting anything actually groundbreaking or thoughtprovoking because I don't think the Joker is a character that can start conversations like that. He's a very surface level guy. Controlled chaos, psychotically smart, with an air of mystery that never goes as deep as "Who is this guy?" which the movie answered anyway. That's the Joker, for the most part. (And I'm still unsure whether the Joker in the movie is supposed to be the Joker, archenemy of Batman considering the massive difference in their age but that's just specualtion on my part) So obviously a movie about him is gonna be dour and dark but not too deep. So I'm interested to see what a musical sequel with Lady Gaga playing Harley Quinn (or at least, this Joker's version of Harley Quinn) will be like.
