I believe the answer is:

casting director

I'm a little stuck... Click here to teach me more about this clue!

'hollywood' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?

'player's fling with straight men drinking mixed gin' is the wordplay.
I cannot quite see how this works, but
'fling' could be 'cast' (I've seen this in another clue) and 'cast' is present in the answer.
'straight' could be 'direct' (similar in meaning) and 'direct' is present in the answer.
'men' could be 'or' (military abbreviation for Other Ranks) and 'or' is located in the answer.
an anagram of 'gin' is 'ing' which is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
