Some familiar faces are returning to "Doctor Who" to celebrate the series' 50th anniversary. Ahead of Saturday night's "Doctor Who: The Companions" season premiere, BBC America announced that David Tennant and Billie Piper, the tenth Doctor and his companion, would be coming back for the show's 50th anniversary special.
Tennant and Piper will join the current Doctor and his companion, Matt Smith and Jenna-Louise Coleman, in the anniversary special, reprising their roles for the first time since 2010.
"Harry Potter" alum John Hurt will also co-star in the special, which began filming in the UK this week.
The news comes on the heels of a report that Smith could be leaving "Doctor Who" after its 2013 Christmas special.
Tennant and Piper's return could help the 50th anniversary special top "Doctor Who's" latest Christmas special, which set a ratings record for BBC America.
"Doctor Who: The Companions" premieres Sunday, March 31, 7:00 at p.m. ET on BCC America.
