Lawyer in film with pained expression shows financial talent (5,5)
I believe the answer is:
midas touch
'financial talent' is the definition.
(I've seen this before)
'lawyer in film with pained expression' is the wordplay.
'lawyer' becomes 'da' (D.A. is an example).
'in' means one lot of letters goes inside another.
'film' becomes 'mist' (I've seen this in other clues**).
'with' is a charade indicator (letters next to each other).
'pained expression' becomes 'ouch' (I've seen this before).
'da' put within 'mist' is 'midast'.
'midast'+'ouch'='MIDAS TOUCH'
'shows' acts as a link.
(Other definitions for midas touch that I've seen before include "Lucrative ability" , "Financial aptitude" , "financial talent" .)
