Naomi Watts star in the upcoming film Diana, and is no doubt sensitive to the nature of the woman and story she will be portraying on the silver screen.
As such, she may be hesitant to discuss it at length.
The 44-year-old actress reportedly walked out of an interview with BBC Radio host Simon Mayo after she may have taken a question the wrong way.
“A first for me and @wittertainment as Naomi Watts walked out of an interview!" Mayo tweeted. "She seemed a tad uncomfortable with the questions. Shame."
“The honest answer is I have no idea. You know my hectoring style is always a problem,” he told a fan who asked what he asked what sparked her exit.
Did you suggest film might not be in best possible taste?" asked Telegraph columnist Allison Pearson, who also interviewed Watts after the Mayo sit-down.
"No, not at all," Mayo said. "Didn't express any opinion. So still baffled."
Pearson said the actress "was heavily guarded" with her responses.
Watts, for her part, has yet to acknowledge the incident.
However, she has admitted that she's anxious about how Diana will be received, particularly by the late princess' two sons, Prince William and Prince Harry.
