The scene is cut even from the online version (begins at 34:00), as is Marcus Aurelius’s death.

I do not recall ever seeing Marcus Aurelius shout that to Maximus in the movie.
In any event in addition to the movie being fiction regarding Maximus, the republic was never restored and Rome was in store for many more generations of despotism.
