can someone tell me what movie this is?

It came out not too long ago, maybe last year i don't think any earlier than that. It was about a A warrior who captured an enemy and forced him to lead the way for him and his troops. I think like they both get captured and have to help each other, or the slaves people capture the warrior. Its like 300/sparticus blood and sand/gladiator/you get the idea. They were traveling in a mountainy setting, wooded t some points. I only saw the trailer.
