Hobbit 3 - Smaug's the original badass. Too much focus on Thorin, although, yeah, he led the original Gang of Dwarves (and Bilbo) through the book.
Nothing in the book about the Elves being in Laketown when Smaug was acting like an ass, at least that I recall. Artistic license, I guess.
Orcs may look badass, but in battle they're pussies.
