When Christopher Eccleston, David Tennant and Matt Smith played the Doctor, each series lasted for 13 episode plus a Christmas special.
Capaldi will once again star as the Doctor this Christmas, the special episode also featuring the first Doctor and introducing the world to Whittaker’s take on the character.
As a result, the series — which will star Jodie Whittaker as the titular character — will only run for ten episodes rather than the usual 12 or 13.
Upcoming showrunner Chris Chibnal has decided to switch up the Doctor Who formula, increasing the average episode length from 45 minutes to an hour.
