In the programme, which can be heard here, Smith talked about how he nearly turned down the role of the 11th Doctor. He said he had had "a wobble" after being told he'd be David Tennant's successor and after seeing Tennant's face on a set of plates. But described playing the role as one of the greatest experiences of his life.
He described Doctor Who fans are a good bunch, saying one of the strangest things he’s been shown is a tattoo of his own face, opposite that of David Tennant's on a woman’s inner thigh
I said what on earth does your boyfriend think? But he was there and he was smiling away.He described the casting of Jodie Whittaker as the thirteenth Doctor as a brilliant choice.
The show relies on big, broad, creative brushstrokes when it's controversial it's alive. It's brilliant, it's high time and she'll be sensational because she has real humanity and she is funny.Smith said the only advice he had given to the new Doctor is advice once given to him which was "listen to no one"
