Hackman later said "we had a lot of problems on that film; I had arguments with Stanley Kramer." Hackman later read a published diary written by Kramer during the making of the film which described Hackman's behavior on set. The actor called the diary "embarrassing but I have to say it was accurate. And he was probably right in his remarks about me. The film we were making just wasn't worth the difficulties I was giving him. The truth is I was in trouble on that film and I got scared."
