Criminal Minds tells the story of a team of profilers from the BAU (Behavioral Analysis Unit) of the FBI. Now in its 10th season, these pros have seen it all and then some! Dealing with the most dangerous serial killers, kidnappers and stalkers in the country, it’s a wonder they are sane themselves. But it makes for some darn compelling TV! To celebrate the return of the show, we’d love for you to take a look at the stars of the popular crime drama long before they were famous. Warning: Epic hair involved.
