A romance, having been rewritten, is in the process of being filmed (2,6)
I believe the answer is:
on camera
'in the process of being filmed' is the definition.
(I've seen this before)
'a romance having been rewritten' is the wordplay.
'a romance' can be anagrammed to 'ON CAMERA'.
But, I'm unsure how this is indicated.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for on camera that I've seen before include "In process of being filmed" , "Being shot" .)
