Charlie Hunnam was emaciated and had lost 20 pounds for the last season of Sons of Anarchy (2008). During auditions, Guy Ritchie was very bothered by his look though he liked his performance and asked him 4 times during the process about his poor physique and ‘What was the heaviest he had been’. Hunnam said that when Ritchie brought up the 4th time, he knew that the physicality of Arthur was very important to Ritchie. He promised Ritchie that he would get into incredible shape for Arthur and to prove his fitness for the part, offered to physically fight the other two finalists - Henry Cavill and Jai Courtney. Hunnam told Ritchie, “Look, dude, you keep bring this up, the physicality. Its obviously your primary concern. So if you want to do away with all this auditioning bollocks, I’ll fucking fight those other two dudes. I know who they are. You can bring them both in here. I’ll fight them both. The one who walks out the door gets the job.” Hunnam won the role after this.
— Charlie proving that you can take the boy out of charming, but you cannot take charming out of the boy xD
