Specialist insight given by Pacino for one acting (11)

I believe the answer is:

provisional

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

'specialist insight given' is the definition.
'provisional' can be an answer for 'given' (thesaurus). I'm not sure about the 'specialist insight' bit.

'by pacino for one acting' is the wordplay.
'by' means one lot of letters go next to another.
'pacino' becomes 'al' (Al Pacino).
'for' becomes 'pro' (as in being 'pro' or in favour of something).
'one acting' becomes 'vision' (I am not sure about this - if you are sure you should believe this answer much more).
'pro'+'vision'='provision'
'al' after 'provision' is 'PROVISIONAL'.

Can you help me to learn more?

(Other definitions for provisional that I've seen before include "Temporary - conditional" , "Temporary - viral poison (anag)" , "Temporary, interim" , "Pending subsequent decision" .)
