8) Sylvester Stallone
Rambo and Rocky star Sylvester Stallone is one of the most impersonated celebrities in Hollywood thanks to his unique rubbery facial expressions and slurred speech.
This is actually something he’s suffered from since birth. Due to a complication, doctors were forced to use two pairs of forceps during the birthing process. Thanks to some shoddy handling of the procedure, this resulted in a nerve being severed which left Stallone partially paralyzed on the left side of his face, specifically parts of his lips, tongue and chin.
Furthermore, the actor has also amassed a ton of injuries over his career which have no doubt contributed to the problem. For one, he was punched so hard by Dolph Lundgren in Rocky IV that his heart began to swell and become compressed against his ribs. Later on, when filming The Expendables, he actually broke his neck when tussling with ex-wrestler Stone Cold Steve Austin.
