Possibly given to Howard, film-maker or wine-maker (8)

I believe the answer is:

vigneron

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

'maker' is the definition.
(I know that vigneron is a type of maker)

'possibly given to howard' is the wordplay.
'possibly' is an anagram indicator.
'to howard' becomes 'Ron' (Ron Howard).
'given' anagrammed gives 'vigne'.
'vigne'+'ron'='VIGNERON'

'film-maker or wine' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Another definition for vigneron that I've seen is " One who grows grapes for winemaking".)

I've seen this clue in the Sydney Morning Herald.
