Having this knowledge, we have to look at what he based his characters on.
Han Solo - Sawyer. I mean, come on
Leia - Kate, rough and tumble babe
Luke - Locke. Our sometimes wimpy, sometimes bad @$$ hero
Chewy - Hurley. The ever loveable sidekick (considered Hurley for Jabba too but didnt want to be mean)
C-3PO - Daniel. Brillant but always confused
R2-D2 - Miles. He's got a smart mouth
Obi-Wan - Christian, Helping our heros from beyond
Yoda - Richard, very old and the only one with the answers
Vader - Ben, still not sure if he's good or bad
Emperor - Jacob, in the end, it all cames down to him
Lando - Hurleys dad, One smooth operating s.o.b
