The 53-year-old played the ninth incarnation of the famous science fiction hero and was the actor who helped bring the show back after its 16 year hiatus.
However, when speaking to Lorraine Kelly, he seemed to have a little swipe at bosses when discussing Doctor Who.
When asked what his thoughts were about incoming Jodie, 35, Christopher said: “Hurrah! The BBC have gone as far as they can with skinny white men.
“God knows how much money they make from it. They needed to reinvent it and they could not have chosen someone better.”
What’s more, he didn’t seem keen on the idea of conventions about the show, which are certainly favourites with fans.
“I’ve never done conventions. But there’s a lot of money there – not that I’m saying anything about those who do attend,” he said.
Christopher explained: “I’ve always wanted to earn my money from acting, but who knows what will happen.”
The actor is currently starring in BBC’s The A Word and plays kind-hearted father Maurice Scott.
However, he has hit out at critics, saying that he feels the programme should be getting more attention for its portrayal of a young autistic boy.
Lorraine airs weekdays on ITV from 8.30am.
