Flicks mince around middle of plate (6)
I believe the answer is:
cinema
'flicks' is the definition.
(I've seen this before)
'mince around middle of plate' is the wordplay.
'around' is an anagram indicator.
'middle of' indicates the central letters.
The middle letter of 'plate' is 'a'.
'mince' with letters rearranged gives 'cinem'.
'cinem'+'a'='CINEMA'
(Other definitions for cinema that I've seen before include "Silver screen" , "Screening" , "Local form of language" , "Odeon perhaps" , "Movie house" .)
