To say “Annihilation” is an adaptation is a loose definition of the word “adaptation.” The film is very much it’s own thing, which made it hard as a book reader to disconnect. “Annihilation” stars Natalie Portman, Jennifer Jason Leigh, Gina Rodriguez, Tessa Thompson, and Oscar Isaac.
Meanwhile “Every Day” is about as faithful as a film can get (with a few creative differences to translate it to screen).
