Find Out When 'Doctor Who' Returns -- And Watch The New, Explosive Trailer

Take a, you know, "Deep Breath" before you watch this one.

When we last left Clara (Jenna Coleman) and the Doctor (Peter Capaldi) at end of the year's Christmas special, "Last Christmas," the bruised and battered duo had finally gotten their groove back after mourning Danny Pink and Gallifrey. And from the looks of the brand freaking new trailer released ahead of the "Doctor Who" panel at San Diego Comic-Con on Thursday (July 9), they're going to stay that way... because this is the most badass, action-heavy "Who" footage we've seen in a while:

Daleks! Missy! Zygons! Menacing eyebrows! Maisie Williams' highly-buzzed cameo! We actually might just explode like the TARDIS did that one time, because this is just way too much.

“Soaring through all of time and space, series nine sees the Doctor throw himself into life with a new hunger for adventure," Capaldi said in a BBC America release. "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.”

And lucky for us, this trailer comes with even better news: a start date! Fans can look forward to more "Who" starting September 19, 2015. Which, you know, might come sooner than you think given the wibbly-wobblyness of time and all that.
