Hey so this movie takes place in ancient greece/rome/persia not really sure. 2014/15 movie i believe. I remember seeing the trailer not too long ago. It had something to do with two brothers who had to choose what to do with the empire. one good brother one bad. I believe it had something to do with freeing the slaves. They end up becoming enemies and fighting.
Just a guess…..”Exodus: Gods and Kings”(2014)
You can watch the trailer here:
