Paul Trefry is an animatronics artist and the director of Creature NFX Workshop. You might recognise his recent working making Percival the pelican for Storm Boy (2019). He has also worked with major film directors such as James Cameron, Angelina Jolie, Russell Crowe, Ridley Scott and Baz Lurhmann.
Animatronics are basically machines that are designed to do specific movements. We are generally contacted by a film producer and sent designs of what they want the animatronic to look like. Then we talk to the director about what the animatronic is required to do, and how he wants to shoot it etc .
