This'll really piss off the Greeks!
Turcophile though I am, I can't say this is in the best taste. Plotting papists notwithstanding, they're really stretching to portray the Ottomans as noble underdogs in this fight. But, historical nuance be damned, the giant cannon and the carrying of the ships over the hill to the Golden Horn are events which really deserve to be portrayed on film, and it wasn't likely to happen in any context besides Turkish nationalism (though John Bellairs' Trolley to Yesterday could make a good movie).
They should do the battle of Manzikert next. I'll bet it could be filmed largely on the actual location too: pretty sure it's still nice and empty out there in Muş. And Alp Arslan with his giant mustaches tied behind his head is surely a dream role for some actor.
