A spat between Ewan McGregor and Piers Morgan has escalated after Morgan called McGregor “a pedophile-loving hypocrite”. The actor pulled out of an interview with a U.K. breakfast show on Tuesday after taking issue with presenter Piers Morgan’s criticisms of the Women’s March last weekend.

Morgan, a former CNN presenter who appeared on President Trump’s show The Apprentice, had earlier said that the marches, held across the world in protest at the incoming U.S. administration, were “anti-democratic.”

McGregor, who is currently promoting a sequel to cult nineties hit Trainspotting, tweeted that he would be dropping out of the interview over Morgan’s remarks:

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”, The Guardian reports. He also sent out a tweet deriding McGregor for being “just an actor”.

Morgan has since published an article about McGregor, which dwells on the actor’s professional relationship with Roman Polanski, the director who fled from the U.S. in 1978 after pleading guilty to the statutory rape of a 13-year-old girl.
