Peter Capaldi Quits Doctor Who

58-year-old, Peter Capaldi announced on BBC's BBC Radio 2 on Monday that he is leaving the BBC drama, Doctor Who. Capaldi said, "I've never done one job for three years before and I feel it's time for me to move on to different challenges". The new season of Doctor Who will start in April, and Capaldi's last episode will be the 2017 Christmas special episode. This leaves viewers wondering who BBC will cast as the 13th Doctor.
