Happens to the best of us, Annie. When I first started out I got sacked by a first-time "director" for pointing out that he was supposed to say "Action!" and "Cut!" to let the actors on set know when to start and finish. Then, on the second day we had no power for the camera because he'd used up all the batteries the night before watching the previous day's takes. I would have happily left him to flounder, had not his producer rung me up ten minutes later and begged me to come back....
...A couple of weeks ago, I shot a showreel piece- as a 'favour' -for an "actress" who wants to be a TV presenter ('nuff said). For her piece(s) to camera, she chose the Life & Works of Bob Dylan. She kept referring to Dylan's "dee-butt"; "As opposed to Cee-butt? What do you mean?" I asked. "Oh, you know", she said, "When you first appear somewhere, you make your dee-butt". - I'm not making this up - Then she went on to refer to the French poet who influenced Dylan as being one Arthur "Rim-board", which, if nothing else, confirms that quote about the French being able to pronounce a lot better than they spell. I still haven't seen the material as, she said, I "made her sound confused and aggressive".
