Harrison Ford worked his charm to the maximum playing our beloved Han Solo (the secret better half of Chewie) and the love of Princess Leia’s life. The fact is that he was originally imagined as a gilled creature, then later transformed into a black character and finally settled for white, with actors like Jack Nicholson and Christopher Walken auditioning for the role (yes, Chris would have been odd, considering he is famous for being a cold-blooded villain).
