A few passionate kissing scenes. There is an implied sex scene near the end, but nothing to serious. There is a scene where Santa Anna wakes up in bed with his sister, who is implied to be nude, but there is nothing inappropriate going on here.

Some Texans get into a drunken fight, this is broke up and they go about their business.

Some battle scenes, nothing too violent. There are a few raids against the Mexicans. The Alamo battle is the climax, nothing too graphic for teens.

Hundreds of people killed.

A few uses of Damn and Hell. I don't remember if there is any stronger profanities used or not.

There is some drinking, but nobody is "drunk". There maybe some smoking of pipes or cigars.

Santa Anna's temper might scare some viewers.
