Sean Penn, "Superpower" co-director, says Zelenskyy changed as Russia invaded: "Like he was born for this"

Two-time Academy Award winner Sean Penn was with Ukrainian President Volodymyr Zelenskyy when Russia invaded Ukraine — as he filmed a documentary that was intended to be about a comedy superstar-turned-president but ended up being about an existential threat to democracy. 

Penn said Zelenskyy changed that day in February last year, and he noticed the shift when the two were together in the bunker of the presidential palace during the start of the invasion.

"I met him the day before and .. when he entered the room on the day of the invasion, to our cameras, ... it felt like he was born for this .. and it was a seamless rise," Penn told "CBS Mornings" on Wednesday. "It was a different person, cellularly, than the one I had met the day before. And he had —  and has — as the Ukrainian people do, just complete resolve."
