Setters like Hollywood productions (6)

I believe the answer is:

aspics

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

'setters' is the definition.
(aspic 'sets')

'like hollywood productions' is the wordplay.
'like' becomes 'as'.
'hollywood productions' becomes 'pics' (I can't justify this - if you can you should give a lot more credence to this answer).
'as'+'pics'='ASPICS'

Can you help me to learn more?

(Another definition for aspics that I've seen is " Jellied preparations".)

I've seen this clue in The Guardian.
