Film boss to urge variety of cue, right? (8)
I believe the answer is:
producer
'film boss' is the definition.
'urge variety of cue right?' is the wordplay.
'urge' becomes 'prod'.
'variety of' is an anagram indicator.
'right?' becomes 'r' (common abbreviation).
'cue' is an anagram of 'uce'.
'prod'+'uce'+'r'='PRODUCER'
'to' is the link.
(Other definitions for producer that I've seen before include "Person who finds the finance for a film (8)." , "One finds the finance for a show" , "Impresario" , "Creator; supervisor (of programme, play)" , "Person who arranges financing for a show" .)
