Sons of Anarchy is gearing up for its final ride—season seven premieres September 9 and looks to be its bloodiest yet. In the latest trailer released by FX, Jax (Charlie Hunnam) is out for revenge, and it doesn't look like everyone is going to survive. Some interesting guest stars have also been announced: Lea Michele of Glee and Malcolm Jamal Warner from Family Matters. Yep, Urkel. 

You might not have to say goodbye to SOA just yet, though: showrunner Kurt Sutter said he's thinking about a prequel. As for Hunnam, he's set to star in the sequel to his movie Pacific Rim and is reportedly working on his first screenplay with Brad Pitt's production company.
