#6- The Battle of Carthage
This was just a classic scene. The story of the fight itself was that the gladiators move. But dudes, they forgot that they put MAXIMUS out in the field. Using some Roman tactics, they manage to beat out the "Romans."
Not only does Maximus showcase some pretty tight twirling with his sword (not seen in recent years except during band competitions) and cause massive amounts of gore to the delight of male watchers, but story wise, this is a pretty riveting scene.
