Re: THE HOBBIT (2012/2013): News, Rumors, Pics Till Release
I would be very surprised if we get a glimpse of Smaug in An Unexpected Journey even in a flashback history tale on Erebor. We might, might a smidgen of him in such a scenario but only enough to tantalize us a la Gollum in Moria in The Fellowship of the Ring.
I think it makes more sense dramatically to wait on showing Smaug. I know the rule is normally to show not tell, but it's not a complicated backstory "there's a dragon who stole our mountain." If I'm not mistaken, it's even in song form.
When on Romulus, Do as the Romulans
