Blanchett gains bloody classification (8)
I believe the answer is:
category
'classification' is the definition.
(I've seen this before)
'blanchett gains bloody' is the wordplay.
'blanchett' becomes 'cate' (I can't justify this - if you can you should give a lot more credence to this answer).
'gains' is a charade indicator (letters next to each other).
'bloody' becomes 'gory' (similar in meaning).
'cate'+'gory'='CATEGORY'
Can you help me to learn more?
(Other definitions for category that I've seen before include "Class, group" , "Genre" , "Class of grey-coat" , "Grey coat (anag.)" , "Type" .)
