Crossword Genius

One appreciates what you did to a hunky cast (8)

Ross

I believe the answer is:

thankyou

'one appreciates what you did' is the definition.
('thank you' shows you appreciate someone)

'to a hunky cast' is the wordplay.
'cast' indicates an anagram (letters are dispersed or cast around).
'to'+'a'+'hunky'='toahunky'
'toahunky' with letters rearranged gives 'THANKYOU'.
