Matt Smith: The Doctor needs an assistant
Matt Smith says Doctor Who's companions are his "moral compass" and help keep the Time Lord grounded and balanced.
Matt Smith says Doctor Who's companions are his "moral compass".
The 29-year-old actor - who has played the Time Lord since 2010 - says his alter-ego always needs an assistant as it helps to keep him balanced.
He said: "The Doctor needs companions for a number of reasons but I'd like to think that it's a lot to do with wanting other people to enjoy the wonders he sees, that way you do when you want a friend to see something you think is brilliant. They're also there to provide a moral compass - though sometimes that bounces around between them, and isn't always as clearcut."
The Doctor's current assistant Amy Pond - played by Karen Gillan - will leave the BBC One show this Saturday (29.09.12) and while he will miss her, Matt says he's been too busy to get upset about it, especially as he's now working with new assistant Jenna-Louise Coleman.
He told Radio Times magazine: "I honestly don't have time. We've hit the ground running with Jenna and it's been non-stop. I've got 10 more weeks of filming before the end of the season and with the 50th anniversary coming up, it's not as if I don't have a lot to think about."
