Yes, it does.
I'm looking forward to Ironclad a lot more than I was looking forward to Robin Hood. Why? Brian Cox. This guy is awesome. Plus James Purefoy, of who I am now quite a fan, Derek Jacobi, Vladimir Goddamn Kulich! That's in addition to setting it during a Medieval conflict that's not about the Crusades or Robin Hood, which is a plus.
Now, there are a few things I'm a bit iffy about: I really hope Kate Mara - sadly not Kate O'Mara, as I mistakenly thought - the requisite Action Chick is fairly believable (i.e. not an 80lb soaking wet waif), Purefoy is really far too young to play Marshall at this point in time, and I'm not sure about those giant double-bitted axes the besiegers were wielding. Plus that tagline on the poster is a bit... well, it's a bit something.
THIS. IS. SPARTA!
Ah well. I still want to see it. There's been a dearth of really good medieval films, especially given the tremendous disappointments of Kingdom of Heaven and Robin Hood.
