Rank Stones "close to perfection" in real life (3-6)

I believe the answer is:

off-screen

'in real life' is the definition.
(as opposed to in film or on TV)

'rank stones close to perfection' is the wordplay.
'rank' becomes 'off' (both can mean rotten).
'stones' becomes 'scree' (scree is a mass of loose rocks on a mountain).
'close to' says to take the final letters (the close/ending of).
The last letter of 'perfection' is 'n'.
'off'+'scree'+'n'='OFF-SCREEN'

I've seen this clue in The Independent.
