It has to be greatly challenging to have a clapboard operator like this, at least if you’re the actor or actress who’s in the scene. I can only imagine how distracting this can be… Nevertheless – this is hilarious. I love the cast’s reaction to what she says. Especially Christoph Waltz’s.
Edit: The “she” is Italian clapboard operator Geraldine Brezca. You can read a bit more about the clip here.
