Russia’s war in Ukraine has often been in the spotlight at this year’s Cannes festival, which is screening several films from Ukrainian filmmakers.
The festival barred Russians with ties to the Kremlin from attending.
On 17 May, Ukrainian President Volodymyr Zelensky delivered a surprise address as part of the opening ceremony of the Cannes Film Festival.
The politician, who was previously an actor, quoted from Charlie Chaplin’s satirical film The Great Dictator.
“The hate of men will pass, and dictators die, and the power they took from the people will return to the people. And so long as men die, liberty will never perish.”
The film festival has yet to comment on the incident nor is the name of the activist currently known.
