Doctor Who season 7 teaser trailer

BBC America has released a teaser trailer for season 7 of the new “Doctor Who,” starring Matt Smith as the Doctor, an alien time lord who travels through space and time in the TARDIS, a ship that’s bigger on the inside than the outside that looks like a 1950s British police call box.

Here’s how BBC America describes the upcoming season:

The new season will see the last days of the Ponds, with Karen Gillan and Arthur Darvill making their final rollercoaster voyage with The Doctor (Matt Smith). Amy (Karen Gillan) and Rory (Arthur Darvill) have been at the Doctor’s side for more than two seasons but what will he do after their heartbreaking departure?

New guest stars so far confirmed to star will include David Bradley, Rupert Graves and Mark Williams. Season 7 will then see a dramatic turn of events when The Doctor meets a new friend – the recently-announced new companion, played by Jenna-Louse Coleman. Prepare yourselves for thrills, adventures and dramatic surprises as the show builds towards its enormous, climactic 50th anniversary year.
