With Joaquin Phoenix officially signed on to play The Joker in an origin movie that starts shooting in just a couple of months, we’re going to be hearing about other castings news soon. Tonight, we got a little taste of what to expect.

According to The Wrap reporter Umberto Gonzalez, this year’s Oscar winner for Best Actress, Frances McDormand, recently turned down the chance to play The Joker’s mom in the movie. According to Gonzalez, Warner Bros. wants a “name” actor for the role, which means they’ll likely be pursuing other Oscar winners and/or popular actors.

Batman’s dad, Thomas Wayne, will reportedly have a big role in The Joker as well.

The Joker begins shooting in New York City in September, so we’ll be hearing more casting news soon. Who would you like to see play The Joker’s mom? Let me know in the comments below.
