Working with Chaplin was very amusing and strange. His films are so funny, but working with him, I found him to be a very serious man. Whereas the films of Hitchcock are macabre, he could be a very funny man to work with, always telling jokes and holding court. Of course, when I worked with Charlie he was getting older.
I sense a kind of fear of writing black or Asian characters from non-ethnic writers, who perhaps feel that they don't know the culture and therefore can't write about it. By and large, if there's an Asian character, I might get a call. But if the character is called 'Philip,' the chances are I won't.
