The closure of Polish cinemas earlier this year, due to the coronavirus pandemic, dealt a temporary blow to the 17th edition of the Millennium Docs Against Gravity Film Festival, which was slated to take place in May. But the organizers were determined to hit the ground running as they geared up for a fall reboot, which will unspool across seven Polish cities between Sept. 4-13 with some 1,200 screenings—“more than at the Berlinale,” notes festival founder Artur Liebhart.
