Sons of Anarchy, FX's thrilling, obsession-worthy drama about a biker prince's rise to power, has gotten an early pickup for a fourth season of 13 episodes. The series, which stars Charlie Hunnam (you may know his abs from the cover of Men's Fitness), Hellboy himself Ron Perlman and give-her-an-Emmy-already-for-the-love-of-god Katey Sagal, is the network's highest-rated series ever, with this season's new eps pulling in about 5 million viewers per week.
