Yes, it's true. Peter Capaldi has retired from playing Doctor Who, with a new Doctor coming next year. But before that happens, we'll still get to enjoy his take on the good doctor in Season 10, which debuts on BBC America Saturday, April 15. Today, the network has released an exciting new tailer.

This year, Doctor Who gets a new companion. Her name is Bill, and she is played by Pearl Mackie. This latest sneak peek at all-new episodes introduces Bill. And she offers her thoughts on working with the man known as Doctor Who.

"The first time you meet him, he's funny. The second time, he's amazing. The third time you realize he's the most dangerous man in the universe. He says he's a man of peace, but he walks in war. I'm having the time of my life. And I wouldn't miss it for the world. Even if it kills me."

Doctor Who Season 10 is the third year for Peter Capaldi, who is the twelfth Doctor to occupy this space on the small screen. This season is the first to introduce Pearl Mackie as Bill Potts, the Doctor's new traveling companion. Also included in this new trailer is Matt Lucas, who plays Nardole. Nardole was first introduced this past December during the Christmas special The Husbands of River Song.

The 12-episode Doctor Who Season 10 was preceded by the 2016 Christmas special. Showrunner Steven Moffat is executive producing Series 10, though it will be his final series with Chris Chibnall set to succeed him. Doctor Who, which began broadcasting on BBC America in 2005, follows the Doctor, an alien from a race called the Time Lords whose home planet is Gallifrey is created by Sydney Newman (The Avengers), and Executive Produced by Russell T. Davies (Torchwood), Julie Gardner (Torchwood), Steven Moffat (Sherlock), Phil Collinson (Coronation Street), Piers Wenger (How I Live Now), Beth Willis (Doctor Who Confidential), Brian Minchin (Wizards vs. Aliens), Caroline Skinner (Our Girl), and Mal Young (Desperate Scousewives).

58-year-old Peter Capaldi revealed he was leaving the series during a recent appearance on BBC Radio 2. While speaking with host Jo Whiley, he confirmed that Doctor Who Season 10 was going to be his last, something that had been speculated previously. He expressed a lot of gratitude for the experience but just felt it was time to move on to different things. Here is what he had to say.

"The big thing about it for me is that it (the new series of Doctor Who) will be my last...I feel sad, I love Doctor Who. It's a fantastic program to work on and it's been a huge pleasure to work with a family. I can't praise the people I've worked with more highly, but I've always been somebody that did a lot of different things. I've never done one job for three years. This is the first time I've done this and I feel it's sort of time for me to move on to different challenges."

You can check out the latest sneak peek at Doctor Who's return in this new trailer, which really belongs to Bill. The Doctor, Bill and Nardole will be back this spring, so get your sonic screwdrivers out and prepare for a long good-bye before welcoming in another Doctor next year.
