When this moment occurred in Infinity War, I had to do everything in my power not to jump up and scream in delight in the theater. Let me explain…

When I wrote Thanos: Titan Consumed, Infinity War was still several months in the future. I knew some things about the movie (Thanos’s motivation, for example, as well as the location of the Soul Stone), but not everything.

(An aside: In my first conversation with my editor after agreeing to write the book, I said to him, “The movie’s gotta end with the Snap, right?” He concurred. I later asked the studio if the movie would end “with Thanos in full possession of the Infinity Stones.” They replied, “I’m not telling you how the film ends!” But I knew I was right. And I was!)

Anyway, I was writing the book without knowing all that much about the movie. Contrary to some speculation I’ve seen online, I never saw a script or spoke with the screenwriters. So I was using what little information I’d been given and then filling in the rest with my own imagination.

And this is a bit I wrote towards the end of the book (spoilers!):

So when Thanos chides Thor, “You should have gone for the head…” I was ecstatic. I had nailed the character, right down to mimicking an element of his personality that I couldn’t have possibly known about. If you’ve read the book and seen the movie, for all you knew, this was carefully coordinated. But it was just the best, most delicious sort of coincidence.
