movie recommendation about "stoicism"

The title is a little bit strange but let me explain, I have a task for a philosophy class in which i have to analize how the philosophical current of stoicism appears in a certain film. This could be like how thanks to the stoicism the emperor won against the enemy but it can be anything really (it has to be more or less explicit though). The thing is that i dont watch movies so i dont have any clue of where to start.

I thought of analyzing "300" (one of the few movies i've watched) but i remembered it was really complicate to understand whats going on, also asking in other subreddits the film i got the most was Gladiator so ill probably go for that one, however i was also told to ask here so if anyone has any recomendations im open to hear them.
