2. Gemma Arterton
This Bond girl's physical defect could have earned her a role in an X-Men movie—the gorgeous star was born with six fingers on both of her hands! This condition is called polydactyly, and it affects about one in a thousand children. The extra digits are harmless if they're left alone, but doctors have a somewhat creepy way of getting rid of them. They tie off the tiny extra fingers, which cuts off their blood supply. The fingers then die and eventually fall off. They can also be surgically removed, but the tie-off method was used to get rid of Gemma's extra fingers when she was just a baby.
