Trivia: There's a notable difference between the trailer and the final version of the movie. The change was made in the scene where the lamp falls down next to Truman. In the trailer, as Truman looks up, he sees a closing hole in the sky, but in the final version of the movie, this hole is replaced by a lamp post. (00:03:50)
