Kurt Sutter's Sons of Anarchy has had some interesting guest stars over the years (Joel McHale, Ashley Tisdale, David Hasselhoff, Stephen King), so the latest addition shouldn't be all that surprising.  Marilyn Manson has been cast in the upcoming seventh season in the recurring role of “Ron Tully, a white supremacist prison shot-caller who Jax uses to expand his power base."  Aside from his musical career, Manson has appeared in a number of films and TV shows, with Wrong Cops and Eastbound & Down being among his most recent acting gigs.  Hit the jump for what he had to say about Sons of Anarchy, plus information on the premiere dates of AMC's fourth season of Hell on Wheels.

Here's Manson's comment on joining Sons of Anarchy:

"Sons has been such a big part of my life, as well as my father's. So I was determined to make him proud by being involved in what will probably be remembered as the most amazing piece of television cinema.  After all, the very heart of SOA is about that relationship.  So, now all I need is a motorcycle."

Additionally, according to TV LineAnnabeth Gish will also be joining the show as Charming's new sheriff, "Althea Jarry, [who] will call on her years of experience in Stockton’s Organized Crime Unit to pursue the murderers of spoiler (if you're not caught up) former Sheriff Eli Roosevelt and Tara Knowles.  "Jarry quickly realizes she’ll have to work with SAMCRO to keep the peace, even if that means playing by their rules. But she has a few of her own that might surprise the club."owles."

While Sons of Anarchy is expected to return this September, hitting the air a bit earlier will be the fourth season of AMC's railroad drama, Hell on Wheels.  As TV.com reports, the Anson Mount-starring series will return Saturday, August 2nd at 9pm for a ten-episode run.  It will then take a break in October while the network's FearFest takes over, only to return on Saturday, November 8th for a bonus round of three episodes. 

Season four sees civilization taming "the West via the Iron Horses that so many men spent the first three seasons building, and that pens in the trusty hands of government bureaucrats will replace guns in the steady palms of 'slingers as the show's weapons of choice. Get ready for 'conflict between government and big business, ranchers, homesteaders, and the railroad' as 'all of those interests compete with one another for control of Cheyenne, Wyoming, the 'Magic City of the Plains' and the most important railroad hub in the country."
