Actor Ewan McGregor was a last minute no-show on the Good Morning Britain television show because of a dispute with host Piers Morgan over recent women's marches.

The star tweeted Tuesday that he pulled out when he realized Morgan was the host of the popular show.

Was going on Good Morning Britain, didn't realise <a href="https://twitter.com/piersmorgan">@piersmorgan</a> was host. Won't go on with him after his comments about <a href="https://twitter.com/hashtag/WomensMarch?src=hash">#WomensMarch</a> —@mcgregor_ewan

He said he was angered by derogatory comments Morgan had made about the massive protest marches that followed the inauguration of U.S. President Donald Trump.

"Won't go on with him after his comments," McGregor tweeted.

Morgan had earlier claimed that the marches were "just an anti-democratic protest at Trump winning the presidency."

He complained on Twitter that it was "unprofessional" for McGregor to not show up for the breakfast show.
