My teacher said it is important to show how the 'creators' of various interpretations reached their overarching rationale from the text. i.e. you need to quote lots and link it to the interpretations and yes it is important to show how you would stage it but as someone pointed out, you show how your interpretations influenced you to form your own opinion about how the play would be staged. good luck. anyone else worried about not getting all their ideas down? i know i am.
