I think my least favorite part of (co-)producing an improv show is the part where I'm emailed the schedules of 11 busy people and I have to figure out when we can all meet for a rehearsal. "Well, if we meet on Thursday from midnight to 2 AM, we'll have most of the group." Between these two rehearsals, I think we got 9 of the 11 to rehearsal, which included no more than 7 at each (if all that math makes sense).
The first rehearsal was the kind of great rehearsal I have dreams about. We all jumped in and really connected and felt a lot better about the form and each other. Yay!
The second rehearsal was low energy and full of bickering. Boo.
