The level of secrecy has increased.
Years ago Apple was the crazy strict one. (and still are) The name "apple" was not even used. When you were booked, production would say the job is "Rose".
And then you'd know you were working for Apple.
They simple don't want anything leaked. No pictures of the spot, no talk about what we were shooting, and certainly no pictures or description of the new product we were making a commercial about! We all sign multi page non-disclosure agreements.
You even have to wear name badges! They are serious.
So, yesterday, during the safety meeting, the 1st AD said that this commercial was 1 slot lower than Apple. Meaning they want complete secrecy. The non disclosure said that if you talk about it in social media, you agree to pay $50,000.
Everyone has an iphone and many people love to talk about what they are shooting.
Heck, I am one of them! So, I have to be careful.
You can take a picture of the food, craft service, the motor home… but not the set, not anyone with costumes, nothing that would give anything away.
Now, after the spot has aired, it's OK to talk about it and post a pic or two. But not before.
So, anyways, life in the film business. Not a bad idea for you to be aware of this.
