Steven Moffat: Companion is key in Doctor Who
'Doctor Who' showrunner Steven Moffat believes the companions are more important in the show than the Doctor
Steven Moffat says the companion is the most important character in 'Doctor Who'.
The showrunner and head writer insists the Doctor needs a human to travel with him through time and space in the TARDIS to help him be a hero and for the viewers to relate to.
He told BBC America: "The story of 'Doctor Who' is always the story of the companion, it's always their story. It was Rose Tyler's story, it's Amy Pond's story - the story of the time they knew the Doctor and how that began; how it developed and how it ended."
Moffat has never liked the idea of the Time Lord - who is currently played by Matt Smith - travelling alone and thinks it would be unhealthy for the character.
He also believes the show is just as re-invigorated by the new companions as much as when the Doctor regenerates and a new actor steps into the role.
He added: "The story begins again, not so much with the new Doctor, but with the new companion. It is their story. The Doctor's the hero, but they're the main character.
"I thought about the Doctor travelling on his own and it always faintly depresses me. I'm not sure what he does on his own but I don't think it would be healthy. He's far too old and he's seen too much."
Current companions Amy Pond and Rory Williams (Karen Gillan and Arthur Darvill) are set to leave the show in the middle of Series 7 and will be replaced in the TARDIS by Jenna-Louise Coleman, who makes her first appearance in the Christmas special.
