Broadcast cunning horror film with Queen and Prince of Wales, say (8-7)

I believe the answer is:

aircraft-carrier

'prince of wales say' is the definition.
(HMS Prince of Wales is an aircraft carrier)

'broadcast cunning horror film with queen' is the wordplay.
'broadcast' becomes 'air' (synonyms).
'cunning' becomes 'craft' (cunning can mean craftiness).
'horror film' becomes 'carrie' (a976 film).
'with' is a charade indicator (letters next to each other).
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'air'+'craft'+'carrie'+'r'='AIRCRAFT-CARRIER'

'and' is the link.

I've seen this clue in The Independent.
