Stunt coordinator Philli Anderson has worked with such actors as Dame Helen Mirren, Asher Keddie, Teresa Palmer and Noomi Rapace, among others, as a stunt double. While the UK-born specialist started her career as a gymnast (not to mention a period on the British Freerunning team), she turned to the performing arts before moving to Australia and establishing her career in the stunt industry.
If you specialise in horses and a horse movie comes to town, you are very likely to be employed. Similarly, if they make a fight-heavy film here and you are a fighter you have more of a chance of getting work. The best way to make yourself as employable as you can, is to work your speciality, but to also be an all-rounder. Of course this takes more training, but it gives more reward.
