Did you know that in Joker?

Did you know that in Joker?, in the original script, the scene where Arthur dances in the bathroom was very different? He was supposed to hide the weapon and remove his makeup in a very nervous state, but this didn't convince either the actor or the director. After all, why would Arthur worry about hiding the weapon? After considering thousands of ideas, director Todd Phillips played a piece of music by the film's composer, and without planning it, Joaquin Phoenix started to dance, resulting in one of the most iconic scenes in the movie. In fact, the whole movie was improvised. The director saw a clown beating up businessmen and told the cameramen, "Screw it".
