At one point, George Lucas had planned the character of Han Solo to be a huge green-skinned monster with no nose and gills. Then Lucas changed the idea of Han Solo to a black human. He auditioned several black actors and even musicians (including Billy Dee Williams) until finally settling on Glynn Turman. But after this he decided to make the role white. Kurt Russell, Nick Nolte, Christopher Walken, Jack Nicholson, Al Pacino, Chevy Chase, Steve Martin, Bill Murray, Robert Englund, Sylvester Stallone, John Travolta and Perry King were all candidates for the role of Han Solo. George Lucas also wanted to stay away from any actors he had previously used in his films. James Caan, Jack Nicholson, Robert De Niro and Burt Reynolds turned down the role. Harrison Ford (who had played Bob Falfa in Lucas's American Graffiti) read the part of Han Solo for screen tests of other characters but wasn't originally considered for the part. During these tests Lucas realized Ford was perfect for the role.
