Excitedly a romance is being filmed (2,6)
I believe the answer is:
on camera
'being filmed' is the definition.
(I've seen this before)
'excitedly a romance' is the wordplay.
'excitedly' is an anagram indicator.
'a'+'romance'='aromance'
'aromance' with letters rearranged gives 'ON CAMERA'.
'is' acts as a link.
(Other definitions for on camera that I've seen before include "Being shot" , "In process of being filmed" .)
