Five words. New Kids On The Block. You either don't know what I'm talking about, or you do and now you feel very old. Before America's middle-favorite Wahlberg brother was playing every brooding cop on film and television, he was part of the boy band New Kids on the Block. Then he disappeared for a while until he silently crept back into stardom through acting.
It might have been very easy to miss his early roles for that fact, but it's surprising so many people miss his role in 'The Sixth Sense' since he's a crucial part of the movie. He plays Bruce Willis' old patient who shoots and (spoiler) kills him in the beginning of the movie. I can understand how people missed him if you take into account the fact that he lost a ton of weight for the role and had a sickly appearance, making him look like the exact opposite of a boy band hunk.
