Jurassic Week: the Dinosaur Input Device


Next up in vfxblog’s Jurassic Week is a brand new oral history on the making of the Dinosaur Input Device. It was this dinosaur-shaped stop-motion armature fitted with special encoders that kept Tippett Studio in the game during the making of Jurassic Park, after its original stop-motion dinos were scrapped in favour of ILM’s CG. This oral history includes a ton of rarely seen behind the scenes images.

Recently on vfxblog, I was able to speak to former ILM animation supervisor Randal M. Dutra about his work on The Lost World: Jurassic Park for that’s film’s 20th anniversary. I invited Dutra back to talk about his stop-motion contributions to RoboCop, which this week celebrates 30 years since its release.

On that film, Dutra was one of the animators of ED-209 at Tippett Studio (others included Phil Tippett, Harry Walton and Tom St. Amand). The enforcement droid was realized as both a full-scale puppet used on set and an articulated stop-motion miniature animated by the Tippett Studio crew, often against a rear-projected background plate advanced one or two frames at a time. Here’s Dutra’s thoughts on helping to make the ED-209 character so memorable. Continue reading “Randal M. Dutra on ‘RoboCop’ and the stop-motion ED-209”

‘The Lost World’ turns 20: Animation director Randal M. Dutra reflects on those early days of the digital age

How Steven Spielberg came to adopt CGI dinosaurs for 1993’s Jurassic Park is an often-told story, including in several interviews I’ve done recently. Ultimately, the move from stop-motion to digital dinos paved the way for an explosion in CG characters in blockbuster movies.

That included Jurassic Park’s sequel, The Lost World: Jurassic Park, released 20 years ago this week, in which the director and visual effects studio Industrial Light & Magic returned with even more photorealistic digital dinos.

One artist who was there on both films, straddling the stop-motion and CG worlds, was Randal M. Dutra. He was at Tippett Studio for Jurassic Park and heavily involved in early movement tests and the use of the innovative Digital Input Device (DID). Then Dutra moved to ILM to work as Animation Director for The Lost World. On the film’s 20th anniversary, vfxblog finds out more from Dutra about his dinosaur experiences.
