New 'Doctor Who' season 8 trailer debuts

Doctor Who fans got a little better of a look at Peter Capaldi -- the newest Doctor -- in the latest trailer for the eighth season of the series.
The BBC unveiled the new trailer Sunday, revealing a bit more dialogue and personality of the 12th Doctor.
"I'm the Doctor," Capaldi can be heard saying over images of a burning Tardis and clips of his enemies. "I've lived for 2,000 years. I've made many mistakes and it's about time I did something about that."
Later his companion, Clara, played by Jenna Coleman, can be heard asking the Doctor, "where are we going?"
"Into darkness," he replies.
Previous trailers for the upcoming season of Doctor Who haven't featured much dialogue from Capaldi, leaving some fans to wonder what sort of personality the new lead will have.
Capaldi recently informed a young fan that he'll take good care of the beloved character, but he'll be "different" from previous incarnations.
