The Making of Instinct
For Stan Winston Studio, John Turteltaub’s Instinct (1999), starring Anthony Hopkins as a renowned anthropologist who lives among a family of gorillas, was more than just another creature effects assignment… it was a chance to prove, once and for all, that the studio’s artists took a back seat to no one in their ability to create utterly believable gorillas.

Creating a Family of Mountain Gorillas
The gorilla family originally included a silverback, a young black-back male and three females — all of which would be realized by performers in suits and animatronic heads — as well as an infant, which would be built as a puppet.

Verne Troyer as a Toddler Gorilla
As shooting neared, the filmmakers decided to add a toddler to the gorilla family, to be performed by diminutive actor Verne Troyer, a relative unknown at the time, who would later gain celebrity as ‘Mini-Me’ in Mike Myers’ Austin Powers: The Spy Who Shagged Me (1999). “Because Verne was so small,” recalled lead toddler gorilla artist Jason Matthews, “I would actually carry him on my shoulders through the jungle where we were shooting. We could just step over a ten-inch root on the ground, but that was a big deal for Verne. I spent most of my time on that shoot taking care of Verne and puppeteering the toddler gorilla head.”

Watching Real Gorillas in Uganda
Prior to starting the design and build for Instinct, Stan Winston joined Turteltaub and the film’s producers on a trip to Uganda to see real mountain gorillas in their natural habitat. Winston returned with videotaped footage of the gorillas, which his artists and technicians used as a bible in creating their characters. “This was going to be art replicating life,” said Winston. “It was very important to me to pick up on every subtle nuance of the mountain gorillas as I saw them in Uganda.”

Committing to Realism With Gorilla Performances
Winston’s commitment to verisimilitude extended to gorilla performance, as well. When performers were cast, Winston and gorilla choreographer Peter Elliott had them carefully study and re-create the gorilla behaviors exhibited in the video footage.

The Magic of Practical Effects and Performance on Instinct
The Winston gorillas in Instinct were so authentic that few people viewing the film ever realized that the animals were not real. “One of the greatest compliments I got from a friend,” said SWS gorilla artist Paul Mejias, “was when he said: ‘I saw Instinct. Which were the real gorillas, and which were yours?’ That said it all.”
