Alien 3 celebrates its 25th anniversary this month, and to celebrate, the Oscar-winning effects house ‘studioADI’ present this gem from deep within the VHS vault.

Footage from the prep and rehearsals of the Bishop puppet shoot complete with direction from David Fincher. Despite the aged quality of the video, it’s still an interesting watch demonstrating the collaboration between director and effects crew on set.
