Second 'Sons of Anarchy' teaser released, exec producer warns of 'controversial' premiere

Don't expect any plot details in the latest teaser for "Sons of Anarchy's" season 6. Titled "Mayham," the teaser shows Jax and the SAMCRO boys riding by a brick wall featuring images of Gemma, Clay and Tara -- which go on to explode.

While no one knows what this means -- more death, possibly? -- executive producer Kurt Sutter told TV reporters at the Television Critics Association press tour on Friday that fans should expect a "controversial" sequence in the September 10 premiere.

“I feel like if it gets leaked, it’s going to be like, ‘oh, they’re doing it to be controversial to bring more eyes to the episode,’” Sutter said. “Honestly, I’m worried more about that kind of blowback than people finding out about that event.”

“I will also say that there’s a lot of blood and guts in my show and it’s the signature of the show," he added. "But I also feel like -- and I feel like I’m not lying to myself when I say this -- is that nothing is done gratuitously. The events that happen in the premiere are really the catalyst for the third act of [the series].”
