That's exactly what British radio host Simon Mayo wondered himself after, according to him, Naomi Watts up and walked out in the middle of an interview for his weekly film program, Kermode & Mayo, on BBC Radio 5.
"A first for me and @wittertainment as Naomi Watts walked out of an interview! She seemed a tad uncomfortable with the questions. Shame," Mayo tweeted yesterday.
The veteran presenter claimed to have no idea what prompted the sit-and-dash.
"What did you ask? Did you suggest she was nuts or something?" tweeted the same fan.
Mayo wrote, "The honest answer is I have no idea.You know my hectoring style is always a problem."
When he was named Speech Broadcaster of the Year in 2008 at the Sony Radio Academy Awards, the honor was described as being for his "ability to paint colorful pictures of location and event and his ability to bring the very best out of his guests, encouraging conversation and interaction between them while skilfully nudging and controlling them."
Watts' camp has not yet responded to a request for comment.
But maybe she just wasn't in the mood to be skillfully nudged and controlled while in the middle of running the press gauntlet.
"So Naomi Watts stormed out of @simonmayo interview today. That explains why she was heavily guarded by the time I went in. Cheers, Simon!" tweeted Telegraph columnist Allison Pearson.
"Apologies then," he replied. "I feel I was probably picking up someone [sic] pieces too."
"Only joking," Pearson tweeted back. "Thought she'd be taken aback by Brit questions. German director seems to think Royal reporting is 'history'. Bless!"
Asked by the columnist if he had suggested that Diana, in which Watts portrays the late Princess of Wales in the final few years of her life, "might not be in best possible taste," Mayo tweeted back, "no, not at all. Didn't express any opinion. So still baffled."
"There was actually quite an eerie moment in London when I did see Prince William in a restaurant, and I got very nervous, because if I caught his eye I didn't want to interpret a look and think he had a negative feeling about this idea, so I made sure not to look," the British actress told the U.K.'s Sunday Times last month.
And in the October 2013 issue of InStyle UK, she says that she "might go into hiding" after the film comes out, which it will, in limited release, on Nov. 1.
Maybe she was just trying to get a jump on traffic yesterday.
