In an interview in the May issue of Arena magazine, Kaufman said: "I was upset by the fact that he took the movie from me and then cut me out after that. I'm unhappy with the end result. And I'm unhappy with George Clooney. I had a movie that I wrote and that isn't it."
Kaufman said when he worked with Spike Jonze on "Being John Malkovich" and "Adaptation," and Michel Gondry on "Eternal Sunshine of the Spotless Mind," the directors kept him involved in the filmmaking process.
"If there's any rewriting to do, I do it. But with Clooney it was different ... even the end of the movie is different. I mean, Clooney went on forever about how my 'Confessions' screenplay was one of the greatest scripts he'd read. But if someone truthfully felt that way then they'd want the person who wrote it to be onboard offering their thoughts and criticisms. But Clooney didn't. And I think it's a silly way to be a director."
The 2002 film marked Clooney's directorial debut.
