I think mine would have to be Truman Burbank, the main character from one of my favorite movies of all time, The Truman Show.
My reason for it is (spoilers for those who haven't seen the movie): Truman is the unwilling star of a 24 hour reality show that has been on the air since the day he was born. Everybody he knows and loves is an actor and everything that has happened to him in his life was scripted. Everything from the death of his father to his wedding. He soon gets curious and wants to explore the world, but he is unaware that he is in a dome where the show is taking place. His will to carry out his goal of exploring is really inspiring and you watch in awe as he realizes the truth about his life.
