Ep 150 | David Dozoretz - Pre-vis Pioneer, VFX Supervisor and Director

In this episode I chat with visual effects supervisor, second unit director and digital pre-visualisation pioneer David Dozoretz about a career that traces the entire arc of how modern filmmaking shifted from analogue to digital — and how, somewhere in the middle of that shift, pre-vis went from a curious side experiment to a fundamental part of how films get planned and shot.

David talks about growing up in Phoenix, falling in love with cinema the day his sister snuck him into the projection booth at the Cine Capri during The Empire Strikes Back asteroid sequence, and how a chance encounter with a Lucasfilm coffee-table book in a university bookstore set him on the path to ILM. He arrived at ILM in 1991 as an intern, became known as "the computer nerd in the art department and the art nerd in the computer department," and ended up bridging the gap between the two as digital began to take over.

We get into his first feature — the original Jurassic Park — his year-long apprenticeship in the legendary ILM art department alongside Doug Chiang, Ty Ellingson, Harley Jessup, Mark Moore and Stefan Dechant, and the time he had to split a $1,400 piece of 3D software into two $700 purchase orders to get round ILM's general-manager sign-off threshold. It's a small story but it tells you everything about the era — digital tools were arriving faster than the institutions running things knew what to do with them.

A big part of the conversation focuses on the early years of digital pre-visualisation. David did the first major digital previs sequence in mainstream cinema — the train and helicopter sequence in Brian De Palma's Mission: Impossible, the work John Knoll asked him to do that's now credited as one of the reasons the sequence got greenlit. From there he went on to spend four years working with George Lucas on The Phantom Menace, building the entire pod race in previs (a 25-minute version that almost no one has ever seen got whittled down to the 9-and-a-half-minute final), establishing his now-famous three rules of previs (no textures, no motion blur, no shadows) and then immediately having to break all three of them to convey the sense of speed and floating in the pod race itself.

There are some lovely George Lucas stories too, including the time George walked into the editing room and reacted to David's droid-factory post-vis with "honestly, I was a little worried about that one — looks like it's gonna work," and the moment when George trailed off mid-sent
