Dead Poet's Society: Carpe Diem!

The main theme of Dead Poets Society is carpe diem, which means “seize the day.” In the beginning of the movie, Mr. Keating tells them this and to make their lives extraordinary. Neil represents this by pursuing his acting career even though he knows that his father would not approve. He takes Keating's advice and talked to his father about him pursuing his dream as an actor. Todd also shows carpe diem when he stands on top of his desk at the end of the movie. Even though Mr. Keating is leaving and the board has made up their mind, Todd takes leadership and proceeds to announce to Keating that it wasn't his fault, despite the fact that he could have been expelled. So, I think Carpe Diem was the main theme for this movie.
