The Omen (2006)

Revealing mistake: When Robert Thorn and Keith Jennings are opening the graves, they are sitting and kneeling on the snow-covered ground. However, none of the snow clings to their clothing, and Roberts light trousers do not get any wet spots on them from the snow, revealing that the snow is fake.

Twotall

Robert Thorn: I never want to see or hear from you again.
Father Brennan: You'll see me in hell Mr. Thorn.
Father Brennan: We'll spend eternity together.

Trivia: In Damien's bedroom, look at the wallpaper. The design looks like a bunch of sixes.
