Screen star in a period of abstention cutting alcohol (9)

Ross

I believe the answer is:

valentino

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

'screen star' is the definition.
'valentino' can be an answer for 'star' (I have seen 'Old star' mean 'valentino' so perhaps 'star' could also mean 'valentino'). I am not certain of the 'screen' bit.

'in a period of abstention cutting alcohol' is the wordplay.
I cannot really understand how this works, but
'in' is present in the answer.
'a' is within the answer.
'period' could be 'lent' (Lent is an example) and 'lent' is located in the answer.
'of' could be 'o' and 'o' is present in the answer.
A single letter 'v' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for valentino that I've seen before include "Rudolph -, twentieth century matinee idol" , "Rudolph -, silent film idol" , "Film star" , "Romantic actor" , "Rudolf --, early film actor" .)
