When last we heard from 'Sons of Anarchy' creator Kurt Sutter, the showrunner teased the possibility of a 'Talking Dead' style talk show and a few new casting announcements, the most recent of which have now come to light. 'The Outsiders' and 'Southland' star C. Thomas Howell and 'Shameless' Steve Howey will soon cross paths with SAMCRO in recurring roles, but as whom?

'Sons of Anarchy' season 6 has already announced a wealth of talent for its upcoming fall season,  but Charming always lives up to its name in accommodating a few new faces. According to TVLine, former 'Outsiders' and 'Red Dawn' teen idol C. Thomas Howell will appear in season 6 as questionably loyal ATF agent Frank Eagan, while 'Shameless' star Steve Howey will also recur over multiple episodes as Hopper, a hardcore north Vegas member who crosses paths with SAMCRO.

'Sons of Anarchy's sixth season will also feature the likes of former ‘The Shield’ star CCH Pounder, ‘Deadwood’ star Kim Dickens, while both Drea de Matteo’s Wendy and Donal Logue’s villainous Lee Toric will return, and Jimmy Smits (Nero Padilla) was upgraded to series regular. Still unconfirmed is the involvement of Billy Brown’s character August Marks, whom Sutter previously cautioned might not be available for the sixth season. Last year, Sutter also told reporters the next batch of episodes would likely open a few weeks ahead in the story, the weight of the season 5 finale’s events still fresh.

Well, what say you? Which of 'Sons of Anarchy's latest guest stars will cause the most mayhem, C. Thomas Howell or Steve Howey?
