Bradley Cooper played a key role editing 'Joker'

After both writing and directing the critically acclaimed remake of A Star Is Born, Bradley Cooper became one of the most respected creative talents in Hollywood.

Especially when this was coupled with his starring roles in the likes of The Hangover, American Hustle, and American Sniper. That’s exactly why Todd Phillips, who Cooper previously worked with on The Hangover franchise, sought the actor to be a producer on Joker.

It turns out that Cooper proved to be a key figure during post production on Joker, especially when it came to editing the film. That’s according to Jeff Groth, who actually edited Joker, and recently told Collider that Cooper provided some much needed insight to improve the quasi comic-book movie.

“We kept this one pretty close to us. We screened it more personally for people and filmmakers. Bradley Cooper definitely came in a couple of times. He was a producer on the movie, but he definitely watched the movie many times and sat with us. We could call him if we got stuck with something and be like, ‘Hey, can you come over and take a look at things?’”

“He doesn’t miss a thing (laughs). He would watch stuff and he would pick out even some of the smallest things and what are some of the things that he can be picked out for us to address. He was definitely a huge help. I think he got a lot more experience in editing than most people would realise.”

Cooper’s input worked wonders, too, as Joker was recently nominated for 11 nominations at the Academy Awards. As a producer, Cooper could even make it to the stage, too, but only if Joker wins the Best Picture gong.
