Who is the braveheart in the film? On the surface, it was Marshall Rooster Cogburn. Maddie was seeking a man with "true grit" who would help her find her father's killer. And, she was confident she had found him in Rooster. But, Maddie confessed later that maybe she had picked the wrong man for "true grit" when Rooster faltered. She had actually found two strong men to fight, but men less than perfect and turned at times by selfishness and money (Rooster Cogburn and Texas Ranger Glenn Campbell/Matt Damon).
Who is the person in the movie with real "true grit," the real braveheart? Unfaltering, courageous, steadfast, persistent, and sacrificial?
It is Maddie herself.
The men served a purpose, helping Maddie with her passion. How did she get such strong men to help and to actually follow her? Her passion. Nothing would get in the way. An attitude of "get on board or I will find someone else." Her noble call to bring her father's killer to justice drew big men to her side. But, she was the one with real true grit, the braveheart in the movie.
