Back in 2005, Reedus was involved in a horrible accident while leaving a concert, when his car was hit by an 18-wheeler. He survived, but surgery left with a titanium eye socket. While he admits he felt self-conscious about the way his face looked afterward, it didn’t take long for him to get back out there and continue doing what he loved – making films and acting. Another interesting fact about the titanium in his head? Reedus says that when it’s hot it makes his face hot and when it’s cold his face is cold.
