David Tennant warned his friend Jodie Whittaker to be prepared for being recognised everywhere once she joined "Doctor Who."
The 47-year-old star - who previously played the Time Lord himself and began his friendship with the 36-year-old actress in 2013 when they started filming "Broadchurch" together - warned her to be prepared for a media frenzy which would follow her taking on the role of the Thirteenth Doctor in 2017.
Speaking on "The Zoe Ball Breakfast Show" on Friday (01.02.19) he revealed: "I didn't really have advice for Jodie. In terms of playing the part, she's all over it, she's such a skilled actor. But, I suppose if we talk about anything it was just kind of "guard your life" a little bit because you are about to lose a certain element of it."
Asked if he had a "disguise" so people wouldn't recognise him in the street, David admitted while he doe try to "keep moving", he doesn't mind being stopped by a fan.
He added: "You just keep moving. It's a very nice show to be known for because people feel very affectionate towards it. "They don't come up and harangue you in the street they are just usually rather delighted so it's nice to be in the middle of that. "
The "Mary Queen of Scots" actor also revealed the role of the Doctor requires a lot of "enthusiasm" as the fans are so passionate and have high expectations.
He said: "It attracts a level of enthusiasm, that particular show, which isn't really like anything else, because it's kind of cross-generational and people have grown up with it. So even people who don't watch it feel connected to it and feel they have an ownership of it.
"And yes, there is a sense of "don't break it. Don't break it on your watch" because it's precious and people love it so much and it does make you ubiquitous! And that's the bit you can't really prepare for."
