Teller talks at the end of the movie, which for many people was the first time they had ever heard the magician's voice.
When Penn Jillette and Teller are abducted by the Filipinos on the beach, Penn says, "Do what you want to the girl, but leave me alone." This line is one of the phrases in George Carlin's list of "Things You Never Hear".
In the scene where Teller is being held down with ropes by audience members, the one closest to Penn is James "The Amazing" Randi. A close friend and mentor, Randi wrote the book "The Faith Healers" and exposed psychic doctors to the public, a driving plot point in the film.
