Doctor Who gets a new companion for his 50th anniversary "Doctor Who" is currently shooting the seventh season of its current run, but lead writer and executive producer Steven Moffat is already looking ahead to next year, which marks the Doctor's 50th anniversary. And as part of the celebration, the Doctor is getting a new companion, actress Jenna-Louise Coleman. Coleman is no stranger to the BBC; she's previously appeared on the series "Emmerdale" and "Waterloo Road." And for those who don't have a penchant for British soap operas, she was on the big screen last summer in "Captain America: The First Avenger." Moffat is promising big things with Coleman, while simultaneously playing it close to the vest. It's not often the Doctor meets someone who can talk even faster than he does, but it's about to happen. Jenna is going to lead him on his merriest dance yet. And that's all you're getting for now. Who she's playing, how the Doctor meets her, and even where he finds her, are all part of one of the biggest mysteries the Time Lord ever encounters. Even by the Doctor's standards, this isn't your usual boy meets girl. But what about Amy Pond (Karen Gillen) and her husband, Rory (Arthur Darvill)? They're in the current season (their third with the Doctor) but the end is looming large and the BBC is describing their departure as "heartbreaking." Meanwhile, the 11th Doctor, Matt Smith will be returning for the show's eighth season, which will mark the character's 50th year on TV. It all began as a black-and-white series in England in 1963 and is now listed in the Guinness Book of World Records as the longest running science fiction series on TV. In addition to the TV series, director David Yates has stated that he's working on a "Doctor Who" movie, though Moffat has said it would have nothing to do with the TV version of the Doctor.
