As a working actor, showing yourself in the best possible light is absolutely critical to getting an agent, a manager, and/or auditions. The #1 way to showcase yourself is through scenes on your reel.
A successful scene must include good: writing, lighting, audio, mic'ing, camera, lens choice, framing, scene partner, directing and editing. If any of these elements are lacking, the scene won't work. Picking the right scene for you is also paramount. The stars really have to align, and if they don't, then you have to find someone who can align them for you.
I love acting and I love actors, so if you're serious about your career (because this ain't cheap), please inquire and let's shoot a great scene for your reel!
