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.
The best advice I can give someone wanting to get into the industry, is to build up a folio of your work that includes things you have made at home. Then try and get as much on the job experience as possible, because there are many ways to do one job, you just need to work out which one is the best for your application.
