My rule is generally first book, then movie. But lately there’s a bunch of things appearing on screens (big and small) that I’ll be watching before reading. Notably:
Crazy Rich Asians by Kevin Kwan
Dietland by Sarai Walker
Sharp Objects by Gillian Flynn
Sweetbitter by Stephanie Danler
and one that I was hoping to re-read before the movie is released (but have accepted that there won’t be time…) – On Chesil Beach by Ian McEwan.
Are you strictly book before movie? Do you hate movie-tie-in book covers as much as I do?
