Why Doctor Who Spinoffs Rarely Happen Explained By Longtime Showrunner

Former Doctor Who showrunner Steven Moffat explains why spinoffs are rare for the long-running program.

The character, a Time Lord from the distant planet Gallifrey, is known to regenerate and has been portrayed by several actors, including William Hartnell, Tom Baker, David Tennant, Matt Smith, Peter Capaldi, Jodie Whittaker, and soon Ncuti Gatwa. Moffat served as Doctor Who‘s showrunner through six installments, and also produced the television series Sherlock and Dracula.
