Spencer Tracy in Dr. Jekyll and Mr. Hyde (Dir. Victor Fleming, 1941) 

“I’ve always been skeptical of people who say they lose themselves in a part. Someone once came up to Spencer Tracy and asked, "Aren’t you tired of always playing Tracy?” Tracy replied, “What am I supposed to do, play Bogart?" You have to develop a style that suits you and pursue it, not just develop a bag of tricks.” -- James Stewart
