I’m surprised it took this long to make a sequel to 300. But when your main character is killed off in the first movie, I guess it would be kind of hard to sell a sequel. That being said, here’s the sequel. Butler-less. No Zack Snyder behind the camera either, though you wouldn’t know that by the looks of things.
300 Rise of an Empire comes out next March. I’d expect something at Comic Con this year for it.
