Action movie I'd heard is dreadful (3,4)
I believe the answer is:
die hard
'action movie' is the definition.
(1988 film)
'i'd heard is dreadful' is the wordplay.
'is dreadful' indicates an anagram.
'id'+'heard'='idheard'
'idheard' anagrammed gives 'DIE-HARD'.
(Other definitions for die hard that I've seen before include "Reactionary" , "Traditionalist" , "Conservative" , "missing the old ways" , "movie?" .)
