Yesterday the “Doctor Who” cast and crew hit San Diego Comic-Con, hosting a panel with fans of the long-running sci-fi show to discuss the upcoming ninth season.

During the event the BBC also confirmed that Doctor Who will return to BBC AMERICA on Saturday, September 19 and released a trailer to get fans excited for the big, two-part premiere. The new season was filmed mostly in Cardiff, production has been underway since the beginning of this year. The last season of Doctor Who was BBC AMERICA’S highest rated season ever, so the new season will have its work cutout for it when it debuts later this fall.

The Doctor (Peter Capaldi) will once again be joined by lovely Clara Oswald (Jenna Coleman). The BBC teased the new season saying, “Having the time of their lives, the pair meet new and old monsters, and go on a journey that takes them to deadly alien planets, creepy underwater bases, Vikings villages, a global Zygon uprising, and leads them through hidden alien dens, to the very end of time itself.”

We do know that the Doctor will once agin run-into Missy (Michelle Gomez), there will also be an entire city of Daleks to deal with, as well as the deadly mercenaries called the Mire.

“Soaring through all of time and space, series nine sees the Doctor throw himself into life with a new hunger for adventure,” explained Capaldi. “The Cosmos is there for the taking, thrilling, epic and enticing, and his to play in. But he’s almost reckless in his abandon. It’s almost like he’s running from something, something that if it ever catches him will turn his life upside down.”

As seen in the trailer and announced earlier this year, Maisie Williams will be guest-starring in a very unique role in season nine. Williams of course is famous for playing Arya Stark in the HBO drama series “Game of Thrones.”

Michelle Gomez (Missy) returns to plague the Doctor and Clara in the season opener, and UNIT are back with Jemma Redgrave and Ingrid Oliver (Osgood) returning to season nine following their popular entrance in season eight.
