When I first heard about this, I wasn't sure how it would work — I mean, David Mamet taking on the world of mixed martial arts? And now, seeing the trailer, I still don't know what to think. On the one hand, there's that patented Mamet dialogue, here delivered both by Mamet regulars Ricky Jay and Joe Mantegna and by newcomers like Chiwetel Ejiofor and Emily Mortimer. But how will it mesh with the mixed martial arts scenes? And it remains to be seen how well Mamet will direct the fights themselves — early word is that they're the movie's most glaring flaw. Also, there's the whole Tim Allen thing. Still, it's Mamet, so I'll give it a chance, especially considering how much better Spartan was than it had any right to be.
