I haven't actually directed my first work yet, but if I could add something to this fun topic it would be this...
Rehearsals - It's all semantics but I count table reads as a rehearsal (1st rehearsal). I would also like to do some character work, build character back stories (2nd rehearsals), then staging and blocking (3rd rehearsals). Depending on the quality of talent that I have I can skip the 2nd rehearsals. Based on the responses here this may seem like too much rehearsing but if the Director has done their homework and thoroughly understands their vision and the why's this should not be nightmarish. There is the risk of mechanizing the action with too many rehearsals, but like I said the Director has to have a feel for this. You cannot, in my estimation, go to the set unprepared (professional actors and crew or not, paid or free) and wastes people’s valuable time and appear unprofessional because you are scared of over-rehearsing or simply hate rehearsals - especially if you are a young director (by young I mean new to the trade). Also while on set, I plan on allowing some time to work with my actors to set up the mood and prep the scene. We are shooting out of sequence for Pete’s sake and sometimes may cut too soon - actors are not machines who can just turn it on and off like that. Speaking of which…
Actors - I am no actor, by any stretch of the definition. But to do my due diligence and home work I am watching Sandy Meisner’s master Class and Uta Hagen’s classes on DVD. If I had the time I would attend or audit acting classes. I believe every Director has to understand where actors are coming from. It helps with the communication, which is huge and cannot be understated. Plus it helps you know how far to push and what you can get from an actor. This is win-win as it can only help solidify the mutual respect that can help you achieve your vision to its fullest. Actors like other members of the crew or department heads bring a specific talent to the collaboration. They deserve every single ounce of respect to interpret and give you what you want - what the picture needs. Just because their interpretation does not match you dreamed up version does not necessarily mean that is bad. They can add value to the overall vision too. I would NEVER dare to disrespect any actor by feeding them lines. If that’s what you want then hire some warm body or get your family to perform for you - not sure how much of that nonsense even friends and family would tolerate. If you need to control things that badly then you should just jump right in front of the camera. Now I am not advocating you let rogue actors hijack your vision. No way. All I am saying is that if you are prepared you can do all of the above and succeed as a team, a team that you, the director, leads.
