Documentary filmmaker Joseph Berlinger won a victory in court Tuesday as a three-judge panel decided to stay a subpoena order for him to hand over hundreds of hours of footage to the oil giant Chevron. Berlinger’s film Crude chronicles the struggle of indigenous Ecuadorians against Chevron’s oil contamination of their land. Chevron has sought Berlinger’s outtakes to help defend itself against an Ecuadorian lawsuit seeking $27 billion in environmental damages.
