Dicky recasts female performer (7)
I believe the answer is:
actress
'female performer' is the definition.
(I've seen this before)
'dicky recasts' is the wordplay.
'dicky' is an anagram indicator (dicky can mean ill or non-functioning).
'recasts' anagrammed gives 'ACTRESS'.
(Other definitions for actress that I've seen before include "Stage performer" , "I might work in Hollywood" , "one with a particular role?" , "Theatrical female" , "dame on stage?" .)
