Romantic movie opening in part of London (7,4,4)
I believe the answer is:
notting hill gate
'romantic movie' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'opening in part of london' is the wordplay.
I cannot quite understand how this works, but
'opening' could be 'gate' (a gate is an opening or entrance) and 'gate' is found in the answer.
'in' is within the answer.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for notting hill gate that I've seen before include "Area of West London" , "Central Line tube station" , "London Tube station - lit neon light tag (anag)" .)
