Ben Stiller called Vlodymyr Zelensky his 'hero' during a meeting with the Ukrainian president in the war-torn country on Monday.
The Hollywood star - who is also Goodwill Ambassador for the UN Refugee Agency - visited refugees in Rzeszow, Poland before walking the bombed ruins of Irpin, Ukraine.
The 56-year old then joined the president in Lviv where they discussed the importance of the world remembering the on-going conflict with Russia - 117 days after it began.
