Roles constantly have to be redefined in any form of entertainment. Look back at the gangster pics of the 1930s and 1940s and the way James Cagney or Humphrey Bogart would play the part. These roles were redefined in the 1970s by Al Pacino and Rober DeNiro. And again in the 1990s by Gary Oldman and Anthony Hopkins.
