In the film The Prestige, Borden's secret is that He has a twin brother. Watching the movie for the second time, I noticed a man looking just like Christian Bale sitting next to Borden at the beginning of the scene where Angier and Borden appear as assistants. Am I mistaken, or is the secret revealed as soon in the movie?
Is Borden's secret revealed as soon as the 11th minute of the movie?

As anyone who has seen the movie will tell you, the Eraserhead baby is the stuff of nightmares. The baby itself is famous for being somewhat of a mystery. David lynch refuses to discus the baby, what it is, how it was created, or why it's so gosh darn creepy. The few comments he has made have been cryptic. Statements such as "it was born nearby" or "maybe it was found" have lead to rampant speculation including theories that it could possibly be such things as a skinned rabbit or a cow, lamb, or even human fetus. The prop itself, nicknamed "Spike", featured several working parts making its eyes, mouth, and ears capable of independent operation. What is the baby actually made of and what evidence do we have to prove this?
What is the Eraserhead baby?

Why is the TV show titled "Game of Thrones" and not "A Song of Ice and Fire?"
