One thing's for sure, though. The Game of Thrones star, who has a guest role this season, shouldn't feel too far from home, since there appears to be some sort of dragon figuring heavily in this season, based on the minute of footage released Wednesday.
"I'm the Doctor, and I save people. Here, now, this is where your story ends," star Peter Capaldi snarls at one point, addressing an unseen foe. If the action-packed teaser is any indication, he and Clara (Jenna Coleman) have plenty of opportunities to do so this season, with cases that take them to Viking villages, alien dens and the end of time.
