I like to pause and give notes as we go along (until full out, off book run thru's,  then I only stop for train wrecks or something that I feel is imperative).  Stopping at the time it happens is a great way to fix/work/set something.  An hour or more later, at the end of rehearsal (or worse. the next day) it's hard for an actor to remember exact details of a move/expression/gesture/motivation/etc.  Obviously I have my own caveats and exceptions, but this is generally how I operate.  Although I do warn the cast early on, because many are not used to working this way and it can be uncomfortable at first.

Please help!!  I need all possible feedback.  I am the ED for my county and am trying to get a production off the ground, however I seem to be getting so many prima donas it isn't even funny.  EX: last night at the first read through I asked them to come and sit around the table (where their characters will be) and just read through.  I got so much slack from this!  The "I will not move my chair again" type of thing!  As E.D. it is my job to step up and take care of business when NO ONE else will.  If I wasn't doing this for them, they wouldn't be doing what they love!  This is my first time directing and I always have their respect....these are my friends too so maybe that's a problem taking direction from me? I have no clue but someone please help me get a handle on this!!  I really appreciate anyones time here.....

Thanks for replying Linda.  Nope , no musical chairs.  Great idea on the food which I will do!  My situation is really one that I feel must be explained in greater length as there are so many more factors involved.  Maybe I can get your ear one day and explain everything involved.  I appreciate your time and ideas very much!  

Deb, I think you have probably hit  the nail on the head!  I will do as you advise.  Hate to be harsh, but sometimes I guess situations call for harshness.  I just need to draw a line between friends/job maybe. this has been on my mind just all day trying to keep peace and get a production off the ground! Sound advise and I thank you.

I took your advise last night les and to my amazement it went beautifully!  I can't tell you how much I appreciate everyone's help on this.  Here's a question for anyone, are there any special things that  the director can do to loosen up the actors before rehearsals? Simple games, tongue twisters? What do most do?
