Film tends to be a director’s medium, so if you’re shooting a MOVIE, he or she has a lot more power and sway. If you’re doing a television (or web series) episode, you’re the final voice on pretty much everything. A good director-for-hire does understand that.
Either way, you’re a producer too and your director should listen and collaborate. If you have things that are very important to you, communicate that up front, but everything about filmmaking is about relinquishing control and expectations. You bring on 10 people, they have 10 different thoughts. Some might be bad, some are better than yours, and you roll with it.
When I “pass the baton”, I do so as much as possible, but there ARE moments I chime in on set with a quasi-director hat on; it hasn’t been an issue because I think the people I work with know that’s part of the deal, so be clear. Let the director know, hey, I have thoughts and I don’t want to step on your toes so let me know if I go to far. Be open to being wrong and be ready to pick what you care about.
