Former Doctor Who star Sylvester McCoy says he had to get his "head around" a female Time Lord - but it's "very exciting".
The show's fans recently got a glimpse of Jodie Whittaker (36) in action in the role for the first time.
Scottish actor McCoy (74), who was in the Tardis from 1987 to 1989, told the Big Issue: "As Doctors, we're a part of a very special club. It's very exciting really.
"At first, I found it strange. I had to get my head around it. Then I thought, 'Oh, you know - wait and see'.
"I have talked to someone who's on the technical side of it and she said Jodie is great and Doctor Who is safe in her hands. Let's hope that's true."
