Parts of Joker: Folie a Deux’s script was torn up during filming and rewritten “on a napkin”

Joker: Folie a Deux is seemingly embracing the Clown Prince of Crime’s skill of chaotic improvisation, with star Lady Gaga and director Todd Phillips both revealing that the DC movie often tossed out its script and started over – during filming.

“We’d very often meet in Joaquin’s trailer and sometimes we would just tear the script up and start all over,” Gaga, who plays Harleen Quinzel in the sequel, told Vogue. “It was a really cool, liberating process.”
