Headshots, showreel and voice reel
Getting started in acting means getting a lot of material together. When you’re applying for a “normal” job all you need is a CV and maybe a suit. To be a successful actor you need much more. At a bare minimum an actor needs:
Headshots: these need to be top notch as they’re the first thing casting directors to look at.
Showreel: it needs to be as good as you can afford, again it’s as close to a CV as actors get.
