Mark Wahlberg is an actor and dancer, but wasn't always like that. He used to be a very naughty young man. During his teenage years he even blinded a Vietnamese man in one eye. Permanently. What a little rascal.

Of course, since his criminal youth Mark has been a singer with Marky Mark and The Funky Bunch, done a quick spot with New Kids On the Block (his brother is Donnie Wahlberg, lead dance mechanic) and has now finally settled down as a serious thespian. He's been in Boogie Nights, Three Kings, The Perfect Storm, The Other Guys and The Fighter. He also got nominated for best supporting actor in Scorcese's The Departed (pronounced de dep-oit-ed).

Despite all this, Mark is probably best known as being completely indistinguishable from his real life nemesis, Matt Damon. Unfortunately this has meant Matt has had to take more and more extreme action roles to make sure directors, other actors and foreign film critics don't get him mixed up with Marky Mark, something that must have been quite upsetting for Wahlberg.
