Michael K. Williams
Michael K. Williams was 25 years old when he was stabbed in the face with a knife, leaving him with a large vertical scar across his forehead. The beating, on the other hand, turned out to be a blessing in disguise: the fresh scar allowed Williams to land more gangsta-style acting roles. On The Wire, he was finally cast as Omar Little, and the rest is history.
Steve Buscemi
Steve Buscemi and Vince Vaughn were having some downtime while filming Domestic Disturbance in 2001 when they were swept up in a vicious bar brawl. Due to the battle, Buscemi suffered potentially life-threatening injuries, which left visible scars on his face and body. Despite this, the tenacious firefighter-turned-actor was back on the job only a few months later, volunteering for the 9/11 relief operation – bravo.
