Revolutionary films with drug dealers (8)
I believe the answer is:
chemists
'drug dealers' is the definition.
(I've seen this before)
'revolutionary films' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'films' becomes 'mists' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'che'+'mists'='CHEMISTS'
'with' is the link.
Can you help me to learn more?
(Other definitions for chemists that I've seen before include "They're trained in the natural sciences" , "They study elements and their compounds" , "Scientists" , "Apothecaries" , "pair of Boots?" .)
