Doctor Who star David Tennant has revealed
his scariest TV moment - an on-screen cook-off with his dad.
Tennant faces terrifying monsters when
the new series of the sci-fi drama starts this week.
But he said going on Ready, Steady, Cook
with his dad, Sandy McDonald, was scarier.
The 34-year-old actor said: "Our episode
of Ready, Steady, Cook is going out on Wednesday.
"You genuinely do it in 20 minutes. I
was surprised because whenever I've seen it I think they do it in four hours and then cut it together.
"It was the most tense 20 minutes I have
ever spent in my life.
"I was with Brian Turner and my dad was
with Nick Nairn, so they did the whole Scottish thing.
"The worst part is when Ainsley starts
talking to you.
"The chef will go, 'Chop them into thin
strips,' and I'm desperately trying to get this right while Ainsley wants to chat about Daleks. I wanted to say, 'I can't
multi-task like this! I am really tense right now.'
"And all the time I'm also worrying about
whether my dad's going to embarrass me."
The first episode of the new series of
Dr Who starring David and Billie Piper goes out on BBC1 on Saturday.
The second episode is set at Balmoral,
giving David a fleeting opportunity to use his Scottish accent before switching back to the Doctor's mockney.
He said: "It's really tricky - your brain
clicks into one way of thinking and it's hard to switch.
"There is one scene where I am talking
about a telescope and I turn round to Rose and speak in the doctor's voice.
"Then I turn round again and speak in
a Scottish voice.
"It was confusing and I had to run through
that in my bedroom a few times."
