Colin Firth has lashed out against plastic surgery and Botox injections, calling the procedures "a disaster" for actors, whose faces he says are "supposed to move."

"Injecting something into your face so it's paralyzed, or cutting bits of it up so that you take any signs of life out of it is catastrophic if you're going to express yourself in any way at all," the 48-year-old 'Bridget Jones' actor told BBC.
