Michael Douglas just learned hes related to another actor and fellow Marvel star at that.

The Oscar winner was already impressed when the revelation landed on Tuesdays episode of Finding Your Roots, as historian Henry Louis Gates Jr. uncovered parts of his lineage Douglas never knew, before the host delivered his most effective discovery.

Your DNA cousin is the actor Scarlett Johansson , Gates told Douglas during the episode .

Douglas and Johansson are both part of the Marvel Cinematic Universe. The two stars appeared in Avengers: Endgame (2019) as Hank Pym and Natasha Black Widow Romanoff, respectively.

Douglas was visibly shocked by the news.

Are you kidding? he asked. Oh, thats amazing. All right. This is cool. This is so cool.

The engrossing PBS series is currently in its 10th season. In it, Gates, who also heads the Hutchins Center for African & African American Research at Harvard University, traces the lineages of actors, singers and other notable figures often to quite visceral reactions .

Michael and Scarlett share identical stretches of DNA on four different chromosomes, Gates explained during Tuesdays episode after surprising Douglas, all of which appear on Scarletts maternal lines, which stretch back to Jewish communities in Eastern Europe.

Douglas is no stranger to famous relatives as his father, Kirk Douglas, was one of the most renowned actors of the 20th century. The Ant-Man (2015) star has been married to Catherine Zeta-Jones since 2000, and his son Cameron is a working actor, too.
