Watch this: Joker character coming to life in final trailer
The previous R-rated record holder was either Deadpool or Deadpool 2 (depending on whether you count Deadpool 2's PG-13 rerelease). The original Deadpool pulled in a gaudy $783 million at the worldwide box office in 2016.
Joker came out early in October and has been on a box office tear ever since. It even set a domestic box office record for an October opening weekend. It was only a matter of time before the Batman-less DC villain took out Reynolds' Marvel Merc with a Mouth.
Reynolds may get another shot at the crown with an expected Deadpool 3 sequel.
There's just one problem: Deadpool has been officially adopted into Disney's Marvel movie family and we don't know what that will mean for the next movie's rating. It might end up PG-13 while Joker runs rampant at the top as the clown prince of R-ratings.
