Obi-Wan Kenobi has spoken.

Jedi Master Ewan McGregor and actual Sith Lord Piers Morgan are feuding on Twitter after the actor pulled out of a morning news show after realizing the controversial British TV personality is a co-host.

The Trainspotting 2 (T2) star was scheduled to appear on Good Morning Britain on Tuesday (January 24), but refused to attend the show last minute over derogatory comments Morgan had made about the Women's March, which took place globally on Saturday, January 21.

After finding out about Morgan's co-hosting gig, McGregor tweeted that he wouldn't "go on [the morning show with Morgan] after his comments about #WomensMarch."

In response, Morgan slammed the actor with the ol' "stick to acting/singing/insert-shtick-here" rhetoric, tweeting at him, "You should be big enough to allow people different political opinions. You're just an actor after all."

Appearing on the show Tuesday morning, the inflammatory talk show host joked about the actor's cancellation, saying, "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... I have to agree with what an actor thinks about a particular issue because they’re actors. And as we know actors’ views are more important than anybody else’s," The Guardian reports.

Later, he tweeted again about the beloved Star Wars icon, calling him the "Kim Jung-un of Hollywood" and taunting that, due to McGregor's tweet trending, he had "made him popular at last."

Over the weekend, McGregor voiced his support of the Women's March,sharing that his own daughters were participating.

He has not yet responded to any of the dozens and dozens of tweets Morgan has posted about him in the less than ten hours since McGregor first announced his Good Morning Britain cancellation.
