I saw this movie sometime around 2011-2014, someone borrowed it from a Redbox, so I would think the movie came out sometime around then.

It is set in a fantasy medieval-ish kingdom. Starts of with a man being a guard, or something similar, to a king and somehow a king became a tyrant (or the king died and his son became the tyrant king?). Some people were killed (tried to run and were killed?) including this man’s family. I think this happened during the winter (unless the kingdom was always cold.) Man pretends to be a drunkard who has lost hope and goes home with a prostitute every night, but really isn’t a drunkard and pays the prostitute without actually spending any time with her and goes home, as he is only putting on an act so the king’s men will think he has given up and is not plotting revenge (but he is).  This man along with some other guys are all in on a plan to overthrow the king. Their job is to make shields and somehow use the rivets in the shield (they looked like viking shields with the rivets around the edges, if I remember correctly) as part of their plan, or messaging system to plan the plan. Something of that sort.

At some point a man on the inside, as they say, has a daughter that is going to be forced to marry the king, but they smuggle the main character guy inside the castle in an ornate mirror so that he can rescue their inside man’s daughter.

I’m quite sure near the end, or at the end of the movie, the group battle the king’s men outside the castle, defeats them, and it show’s the main guy ready to go into the castle to kill the king.

I apologize for all the parentheses and run-on sentences, I typed it up as my brain remembered things.
