Hair is very, very distinctive. I started that with that boxing movie I did, The Great White Hype. The director wanted me to look like Don King, and everybody knew who Don King was. But I didn't want to be Don King. I wanted the man to be Rev. Fred Sultan, so I decided to make him look like Julius Caesar. And from that point on, I just decided, I had this great wig-maker, so I just found hairstyles that I felt would be distinctive for every character. Like an adventure.
