The most important message of the movie is that the bonds of brotherhood and family should be stronger than greed, competition, envy. The king also espouses the idea that a great leader does what's right even if it's not popular.
As in most action adventures, there are a lot of chase scenes -- in the desert or marketplaces or castles. There are definitely deaths -- due mostly to swords and knives, and in one case an assassination by a burning cloak -- but the violence isn't grisly or overly bloody. The threat of violence is always present, however, and the assassin squad is creepy and frightening. They use snakes and ninja-like sword skills to track down and kill their intended target.
Some flirting, mild innuendo, revealing outfits, and a couple of rather chaste kisses. In one scene, a harem-like group of bikini-clad women appear.
Some mild insults like "trash," "illiterates," "slave," etc.
There are no product placements in the movie, but the movie could be considered one huge tie-in to the popular video game.
A character asks "Have you been drinking," when an archer misfires. Dastan looks a bit tipsy in one scene, but there's not a drink in his hand.
