New ‘Who': The Trailer for ‘Doctor Who’ Season 7 (Video)

The preview focuses on the season's Western-themed season premiere

Doctor Who is getting a new companion during the show's upcoming seventh season, and if the new trailer for the season is an indication, it's also going to be an action-packed time in the Doctor's life.

The trailer for season seven — which will premiere later this year and will tie in with the classic British series' 50th anniversary in 2013 — highlights the Western-themed season premiere episode. It will look at the last shared adventures of Who (Matt Smith) and Amy Pond (Karen Gillan) and her husband, Rory (Arthur Darvill).
