Feature from wartime film director Lee (8,7)
I believe the answer is:
anderson shelter
'feature from wartime' is the definition.
(shelter from bombing)
'film director lee' is the wordplay.
'film director' becomes 'anderson' (film director Wes Anderson).
'lee' becomes 'shelter' (the lee is the sheltered side of something).
'anderson'+'shelter'='ANDERSON SHELTER'
(Other definitions for anderson shelter that I've seen before include "refuge from bombs" , "cover from bombs" .)
