The official Jonah Hex site has a flash opening that is a second trailer. We get mostly the same scenes with a few extras tossed in. We have more of a fistfight between Jonah hex and Quentin Turnbull that involved Hex beating the crap out of Turnbull with his own eagle-topped cane. We also have several more scenes of Burke (Michael Fassbender) in hand to hand with Hex.
Check it out, it's worth a look.
