I hadn't heard a thing about this, then I read of the cast and got interested, then I found this summary when I was idling along looking for news on characters from HBO Rome (Kevin McKidd is in it, plus Ben Kingsley and Colin Firth). Opens in April, I believe.

The Last Legion

Whenever they have cloaked characters turn out to be scantily-clad warrior women, I have DIRE worries. Then I read the plot summary . . . oh boy. We shall see!
