Hollywood actors Sean Penn and Ben Stiller were sanctioned by Russia on Monday as retaliation for their vocal condemnation of Moscow’s conflict in Ukraine.

The performers were on a new list of 25 Americans, including politicians, business leaders, and trade officials, who were subject to penalties and barred from entering Russia.

Stiller and Penn have been vocal supporters of Ukraine in the conflict and have met Ukraine’s President Volodymyr Zelenskiy in high-profile shows of support.

In a televised meeting in Kyiv in June, Stiller, star of “Zoolander”, “Meet the Parents” and “Dodgeball”, told Zelenskiy: “You’re my hero.”

Two-time Oscar winner Penn was in Ukraine recording a documentary when Russia invaded on Feb. 24. He was forced to flee on foot, joining the millions of Ukrainians crossing into Poland in the first days of the war.

He has been a vocal backer of Zelenskiy since, returning to Ukraine in June to meet the Ukrainian leader. Penn also visited Bucha and Irpin near Kyiv, the sites of alleged atrocities against civilians by Russian forces, and Zelenskiy has publicly thanked Penn for his support.

Russia denies targeting civilians in what it calls a “special military operation” to protect Ukraine’s Russian-speakers from persecution and defuse a Western threat to its security. Kyiv and the West say these are baseless pretexts for a war of aggression.

The sanctions freeze any Russian assets that those on the list have, prohibit Russian citizens from doing business with them, and ban them from travelling to Russia.

The list also included U.S. Commerce Secretary Gina Raimondo, four deputy commerce secretaries and six U.S. senators.

The West has imposed an unprecedented barrage of economic and personal sanctions on Russia in response to its invasion of Ukraine.

Moscow has retaliated with tit-for-tat sanctions on politicians, business leaders and cultural figures who it says are hostile to Russia.
