While a guest on The Tonight Show with Jimmy Fallon, Gyllenhaal talked about the experience and how his agents neglected to tell him that he needed to do an English accent for the role. This big oversight led to a pretty disheartening experience for any actor. The actor recalled:

“Jackson literally turned to me and said, ‘You are the worst actor that I have ever seen.’ He said, ‘Did anyone tell you you were supposed to have an accent?’ I was like, ‘No!’ And he said, ‘Well, fire your agents.’”
