Sean Penn presents an up-close view of the war in Ukraine in 'Superpower'

As polarizing he might be, Sean Penn is no stranger to humanitarian efforts and crusading around the globe, as detailed in the documentary "Citizen Penn." Penn was in Ukraine when Russian bombs started falling in February 2022, which turns "Superpower" into a powerful chronicle of Ukrainian courage and resistance, in a way that reflects Penn's passion as opposed to journalistic detachment.
