Pandora’s Box has been screened numerous times in the years since its rediscovery, and perhaps nowhere more often than in the San Francisco Bay Area.One of those screenings was witnessed by a local music producer, David Ferguson, another by a silent film enthusiast, Angela Holm. And although the prints they saw were in need of considerable work, both were mesmerized by Brooks’s performance. Together, their efforts led to the exquisite restoration screening at this year’s festival.
