Merciful Zeus, it's finally here! After leaving all those unable to attend Comic-Con 2013 in the lurch, the BBC has finally delivered 'Doctor Who' fans something they've waited months for: a full trailer for the upcoming 50th anniversary special "The Day of the Doctor," with actual footage and all? Allons-y and geronimo, here we go!

"I've had many faces, many lives," says Matt Smith's Eleventh Doctor in the opening moment of the BBC's new spot for the November 23 event. "I don't admit to all of them, there's one life I've tried very hard to forget." Amid snazzy new shots of the infamous Time War, Gallifrey, Daleks and Zygons, we also hear John Hurt's mysterious "Dark Doctor" relay that "Great men are forged through fire. It is the privilege of lesser men to light the flame."

Plenty of humor to be found between David Tennant and Matt Smith's Doctors as well, comparing Sonic Screwdrivers, fashion choices, even the TARDIS interior. And, who could forget the return of Billie Piper as Rose Tyler? Says the BBC of the upcoming special:

The Doctors embark on their greatest adventure in this 50th anniversary special. In 2013, something terrible is awakening in London’s National Gallery; in 1562, a murderous plot is afoot in Elizabethan England; and somewhere in space an ancient battle reaches its devastating conclusion. All of reality is at stake as the Doctor’s own dangerous past comes back to haunt him.

Meanwhile, the BBC will release two short minisodes in anticipation of the landmark anniversary event, titled “The Last Day” and “The Night of the Doctor,” respectfully. Their content and release dates have been kept under wraps, though it’s been speculated one may be released on November 15 during the annual ‘Children in Need’ telethon, as had been suggested previously.

Elsewhere, the 23rd will also see the airing of a special by Professor Brian Cox on BBC Two about the science behind the show, coupled with ‘Sherlock‘ star Mark Gatiss’ ‘Doctor Who’ origins movie, ‘An Adventure in Space and Time.’ “The Day of the Doctor” itself will also be simulcast globally, and released in select US theaters for a 3D broadcast.

Take a look at the first full trailer of the ‘Doctor Who’ 50th anniversary special "The Day of the Doctor" above, and give us your thoughts in the comments!
