A lot of people think "Shawshank Redemption" is the perfect film. It's definitely one of the best ever film adaptations of Stephen King's work, and many people don't even realize the famous horror writer is the author of the original text. Whilst it is an incredible movie, it's not quite perfect. There's a tiny little mistake, hidden away.
The Governor of the jail looks like the sort of man who has impressive attention to detail, but even with a magician's sleight of hand, he couldn't have achieved this trick so quickly. He unloads a gun, and the bullets fall out of it, scattering all over his desk. Mere second later, they're neatly lined up next to each other in front of his pen. It seems unlikely that a man would simultaneously have such a fixation on keeping his desk so clean, and yet not notice that someone was spending years digging a tunnel out of their prison cell, so we're saying it's a blooper.
