I'm going to share a story here that might stretch some of my code as it will include a little bad-mouthing, but there will be no names involved and enough time has passed that these individuals probably won't recognize themself in the work. That being said, you never want to be the person about whom people say, "I will never work with him/her again!!"
I knew I was in trouble on this one shoot when absolutely everybody on set was nice, except the person who cast me. When I went to the make-up artist, his words were, "Girl, you look too much like an Irish princess. You are not getting on camera..." I was completely confused, as that was almost what I was cast for - random Irish clan-type - and they did the costuming. I hoped he was exaggerating.
Later in the day, when we're already behind schedule, it turns out the director and lead had disappeared from set. For about an hour. I'm still not sure what happened or why, but I do know that there was a mini-coups in that period during which about four key crew people mentioned desire to walk off set. After getting through that period, them and more started uttering the "I'll never work with him/her again's".
After an unnecessarily long shoot day, that was further elongated by nobody knowing if we were wrapped or not, I was finally dismissed and made my way home. Not only have I been unable to get in touch with those in charge since this, but even photos that were taken of me in wardrobe have been denied (whereas much of the rest of the cast appears on the actual film site and other social networking platforms). I guess it stinks I fit the type for which they cast me? I'm still scratching my head on this one...
I made a lot of awesome connections at this shoot, so I'm not complaining, but I will now pay more attention when people say, "I will never work with him/her again!" as I now know the feeling.
