'Joker 2' Will Be a Musical, Lady Gaga In Talks to Play Harley Quinn

Joaquin Phoenix’s involvement is not a done deal…

Todd Phillips, the movie’s director, has already teased Joaquin‘s involvement in the movie, but THR reports that it’s not a done deal yet.

Sources told the outlet “that Warners has yet to close a deal with the actor, with the two sides deep into it.”

Gaga‘s possible casting makes sense as Todd previously produced A Star Is Born and her co-star Bradley Cooper is a producer on the Joker movies. Keeping it in the family!
