While the central story of Dwight and his dame is based on the books by Frank Miller, a big part of what's exciting about the new "Sin City" movie, subtitled "A Dame to Kill For," is that two of its overlapping threads, including the one starring Joseph Gordon-Levitt, are entirely new.

So who knows what could happen in this exclusive clip from "The Long Bad Night," the new "Sin City" yarn featuring Gordon-Levitt as Johnny, a gambler whose bravado brings him a lot of luck, both good and bad?

One night in Basin City, Johnny beats the wrong man at poker, and as anyone who's seen a gambling movie knows, that means a beating is coming back his way. But Johnny's not going down without a fight.

Check out the clip from "Sin City: A Dame to Kill For" above. The movie hits theaters on August 22.
