The length of the play precludes more than 6 performances a week so 25% of your gross is gone right then.
The plays themselves while admirable, are repetitive.
Which brings us to a production I saw at Long Wharf in December 2002 with Jane Alexander. The dramaturg had cut nearly 50% of the play and frankly (Scarlett), nobody missed a damn thing. The running time was 3:15.
Maybe more regionals, universities and non-profits could use this adaptation. The problem is that there might be a fight between the purists who want all the playwright's words and the practical who do not want a butt-numbing 5 1/2 hours.
Also NY City Opera did a production of the operatic version a year ago and it worked very well.
