The latest news out of the TCA press tour is that CBS has renewed Under the Dome for a second season. I'm not sure if this surprises me or not. On the one hand, Under the Dome was planned as a "limited series event," meaning that there is supposed to be a resolution at the end of the twelve episodes. On the other, it is the highest rated summer premiere on any network since 2000 - and money talks.
On the upside, producer Brian K. Vaughn has tapped Stephen King to write the season two premiere. According to the Hollywood Reporter:
"When we first started talking to Stephen, we came up with the idea of the town potentially being trapped for years at a time, and that's something that [King said] you guys could get to do that I didn't," Vaughan told reporters ahead of the premiere, noting it might necessitate a different ending to the series. "We pitched Stephen a far-out, big-swing idea for this to go several years -- a different ending -- and he was really excited by it."
Under the Dome season two will begin next summer.
