'film' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'star's good about bloody kiss' is the wordplay.
'star's good' becomes 'reg' (I am not sure about this - if you are sure you should believe this answer much more).
'about' is an insertion indicator.
'bloody' becomes 'gory' (similar in meaning).
'kiss' becomes 'peck' (pecking is a kind of kissing).
'reg' going within 'gory' is 'gregory'.
'gregory'+'peck'='GREGORY PECK'
