We often watch a show or a series quite fast and after 2 month the season is over. But people often forget how long it takes to make and be part of such a production. It begins with a preparation period, then you shoot and in case of a theatre play you train for it. When you are fast and in time you can do an episode of a series in 2 weeks. A theatre play needs around 6 weeks to be prepared before you do a daily performance.
What I want to say with all this?
Well you can spend lots of time for a production and the result is 3 or 4 projects a year, sometimes even less. So the schedule of GA can be very full (as it actually is) and nevertheless it seems as if there are not so much projects. But I can tell, she is very well booked. I wonder how she can manage this amount with her private life.
