Prompt: A Book Made Into a Movie I've Already Seen
"I loved the film and the book equally. Usually I prefer to read the book before seeing the film, but having seen the film did not spoil my reading (although of course I couldn't avoid picturing Matt Damon as the main protagonist). The book has loads of scientific detail in it, which as a science teacher I found fascinating. Easy to forget that humans haven't been to Mars yet and this is not a memoir!" — Rachel
