'The Cherry Orchard' is a masterpiece, and there can never be too many adaptations.
'Sons of the Prophet' is a dark comedy about human suffering. The play explores the particularly messy portions of life - the times where you find yourself coping with multiple life issues, and before any of them can be resolved, two more show up on your plate. We've all been there, I'd wager.
I definitely prefer to write under my own volition and see what happens.
Under Todd Haimes' leadership, Roundabout created a black-box theater whose sole mission was to house premieres by writers who are just starting out and have zero name recognition.
