Ewan McGregor was scheduled to appear on British morning news show "Good Morning Britain" for an interview on Tuesday.
But when he realized the host was Piers Morgan, he abruptly canceled, The Guardian reports.
McGregor was promoting "T2," the sequel to "Trainspotting." But he said he wouldn't go on air with Morgan, who has been critical of the Women's March. Morgan later fired back, calling McGregor "just an actor."
Here's McGregor's initial announcement.
And here's Morgan's response.
WATCH | On air, Morgan said, "Sorry that Ewan McGregor's not here. He couldn't bear the thought of being on the sofa with me because he doesn't agree with me about the women's march. ... As we know, actors' views are more important than anybody else's."
I'm planning a 'Men's March' to protest at the creeping global emasculation of my gender by rabid feminists. Who's with me?— Piers Morgan (@piersmorgan) January 21, 2017
On the day of the march, Morgan said he was planning a "men's march" in protest.
I'm also opening a new clinic, Trump Tantrums Anonymous, for demented Donald-haters.— Piers Morgan (@piersmorgan) January 21, 2017
No fee for celebrities because they love freebies.
He also criticized detractors of President Trump, calling them "demented."
And he bashed the march itself.
He quickly drew a lot of criticism for his tweets.
