Even though Joker, which is the number one R-rated movie of all time, doesn’t currently share a cinematic universe with any other DC/Warner Bros. movie, director Todd Phillips is curious as to what a Batman movie might look like if it was set in Joker’s Gotham.
Per Variety, Phillips, while at the Palm Springs International Film Festival, said “It’s a beautiful Gotham. What I would like to see someone tackle is what Batman looks like from that Gotham.”
