BBC America releases a new trailer for the upcoming tenth season of "Doctor Who". The first-look trailer comes just a few hours before the series' Christmas special airs on Sunday, December 25 on 9 P.M. ET, AceShowbiz said.

The footage for the new season set to premiere in April gives glimpses at the Doctor (Peter Capaldi) and his new traveling companion, Bill Potts (Pearl Mackie). Bill looks fairly befuddled while traveling through time and space with the Doctor.

"Doctor Who" Christmas special, titled "The Return of Doctor Mysterioso", will follow the Doctor and Nardole (Matt Lucas) as they team up with an investigative reporter (Charity Wakefield) and encounter a mysterious figure known as The Ghost (Justin Chatwin).
