Exciting book or film (8)
I believe the answer is:
thriller
I believe this is a double definition.
'exciting book' is the first definition.
(I've seen this before)
'film' is the second definition.
(thesaurus)
(Other definitions for thriller that I've seen before include "Exciting novel/film, etc" , "best-selling album" , "Suspenseful adventure story" , "exciting event" , "exciting work" .)
