Open gothic novel suitable for a film? (10)
I believe the answer is:
photogenic
'suitable for a film?' is the definition.
(photogenic means looking good on camera)
'open gothic novel' is the wordplay.
'novel' is an anagram indicator (letters in a new or novel order).
'open'+'gothic'='opengothic'
'opengothic' with letters rearranged gives 'PHOTOGENIC'.
(Other definitions for photogenic that I've seen before include "attractive image" , "Attractive on camera" , "Looking good in pictures" , "Attractively presented by the camera" .)
