Parsing fail once again -- 13d "Writer projecting parts for audience in Pirates of the Caribbean" ?U?C?N?E?S must surely be BUCCANEERS, but all I can come up with is partial anagrams, i.e. SEER = audience
SCENE = parts
? = writer
(Though I did learn that a buccan is a mythical Cornish water spirit, which seems a bit of a lost opportunity clue-wise!)
