An actor's voice is as important - if not more so - than their look when it comes to casting. Film makers have more options than stage - for example the voices of many of the Bond girls in the first 007 films were re-dubbed by German-born British actress Nikki van der Zyl - even Dr No's Ursula Andress. But that's the extreme - actors need to not only have appealing and versatile voices, they also need stamina. All these skills are taught by Kirstie O'Sullivan, the former Head of Voice for The Actors' Program in Auckland who now has her own business called The Voice Practice..
