“The war seemed impossible, but today it’s part of all our lives,” said director Olmo Parenti on the sidelines of a screening of his documentary about Ukraine, “Crazy Enough to Stay,” with Giorgio Gori, a Democratic Party MEP. The director said the idea for the film arose from a simple reflection: whether he would ever stay in a country at war and living under bombs, emphasizing that his peers in Ukraine are forced to fight for their lives.
