If you see 'The Shining' with Jack Nicholson, you remember him not only because he is Jack Nicholson and because he does a wonderful job, but because he is a threat. The bad guy is someone people will have in their minds forever if it's a good bad guy.
My label is to play bad guys of Latin origin in American movies. I'm happy with that label. I prefer to play that than to play a city boy. The bad guy is always something very tempting for the audience.
