One of the movies along with line that I love is The Truman Show. The movie's plot is that Truman (played by Jim Carey) has lived his entire life in a completely constructed reality-all of the people in his world are actually actors playing roles in a television show broadcast to the rest of the world outside of Truman's artificial world, called "The Truman Show." Truman gradually begins to discover the truth of his situation and escapes from his artificial world, as the rest of the television viewers outside watch and cheer him on.
Here is a trailer for the movie:
