Film bagging Oscar is not dry (5)
I believe the answer is:
moist
'is not dry' is the definition.
(moist means damp or wet)
'film bagging oscar' is the wordplay.
'film' becomes 'mist' (to film over is to mist or fog over).
'bagging' means one lot of letters goes inside another (I've seen this in other clues).
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
'mist' going around 'o' is 'MOIST'.
(Other definitions for moist that I've seen before include "Dampish" , "sloppy" , "Slightly wet, damp" , "Damp, humid" , "Affected by tears, perhaps" .)
