Warning — abridged Hitchcock film is of little value (3,3,5)
I believe the answer is:
for the birds
'of little value' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'warning abridged hitchcock film' is the wordplay.
'warning' becomes 'fore' (used to warn of airborne balls on a golf course).
'abridged' means to remove the last letter.
'hitchcock film' becomes 'the birds' (Alfred Hitchcock film).
'fore' with its final letter taken off is 'for'.
'for'+'thebirds'='FOR THE BIRDS'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for for the birds that I've seen before include "Might corn be" , "easily discarded?" , "Trivial" , "contemptible" , "Deserving of disdain (slang)" .)
