BBC Radio Five Live played the audio clip that appeared to show Naomi Watts walking out of an interview with Simon Mayo.
The actress was promoting ‘Diana’ - in which she plays the late Princess of Wales - on ‘Kermode and Mayo’s Film Review’.
In the excruciating segment, Mayo asks her whether they got permission to film outside Kensington Palace for a sequence showing the floral tributes after Diana’s death.
Watts responded tartly: “Yes we did get permission”. After Mayo asked her to elaborate, she said: “I think we’re getting the wind-up, I’m really sorry but it was nice talking to you.”
Mayo says they still had one and a half minutes of the ten minute interview to go, but Watts says they are running late, and anther female voice tells him to “wrap it up”. Listen to the full exchange above.
Speaking after the interview on the show, Mayo said: "I think it's fair to say that Naomi sounded quite cautious and defensive through most of the interview," he said. "They wanted to do the interview with the director [Oliver Hirschbiegel] present, in case I asked any crazy questions about how Diana died.
"There was no intention and no point in asking those questions, because the film's not about that. So we gave that insurance, and she does the interview on her own, and I think she was a little bit nervous about that.”
A spokesperson for the film company Entertainment One denied that Watts walked out.
‘Diana’ is released in the UK on September 20. Watch the trailer below.
