Somewhere for the players to hear script that's rewritten (9,3)
I believe the answer is:
orchestra pit
'somewhere for the players' is the definition.
(area for the orchestra in a theatre)
'to hear script that's rewritten' is the wordplay.
'that's rewritten' is an anagram indicator.
'to'+'hear'+'script'='tohearscript'
'tohearscript' with letters rearranged gives 'ORCHESTRA PIT'.
(Other definitions for orchestra pit that I've seen before include "Place for theatre musicians" , "wind down in one" , "space for musicians" , "Part of a theatre" , "Area in front of stage" .)
