Laughing Squid explains:
Contributing to Batserds’ growing aura of cult status is the above DVD special feature comprised of Italian clapboard operator Geraldine Brezca who does hilarious, foul-mouthed, and wonderfully sharp scene calls just before clapping for “action.”
Typically when a scene number is called the clapboard operator will follow the English alphabet, and each film set will have their own variation such as using names in alphabetic order, or the International Radio Operator Alphabet (Alpha, Bravo, Charlie, etc.). Not Brezca, “the Clapper Loader and Tarantino’s Camera Angel.” She’s been working with Tarantino over the course of several films and has her own style — which as you’ll see, tends to either shock or compel the actors, or both. After the second viewing, we think there is a method to her madness, even if you think that shouting “Dario Argento” or “Scene 34 Blowjob!” at actors seems random.
