A 'Novelização Oficial' de Star Wars: The Force Awakens foi baseada puramente no roteiro (escrito)?

De acordo com esta entrevista com Yahoo Movies ;

Foster baseou a novelização em grande parte no roteiro de Kasdan:

What level of security was required for you to access the script? In my imagination, it involves a flash drive that self-destructs after two hours.

They didn’t say that, but then, that would be part of the secrecy! [Laughs] No, there are a couple of systems that studios use now to send stuff like that. It probably makes the encryption at the NSA look amateurish. It was sent in pieces to me via email, and it was very, very secure. I used the same system when I did the novelizations of J.J.’s two Star Trek movies, so it was quite easy.

Ele não chegou a ver o filme com antecedência, mas ele foi mostrado alguns dos adereços, arte conceitual e definir fotos

Were you at least shown the film in advance?

No, I just saw it on Saturday morning, the day after it opened. Unlike the two Star Trek films, I didn’t get to see the film while I was writing, which was a shame — it would have made the novelization even better. It always does! I did get to see a fair number of still photos of the settings and the characters in costume. I really made a case for that. I told the studio, “The screenplay describes Rey’s scavenger outfit as being a certain way, but it would be useful if I could see the thing instead of having to invent it — pun not intended — out of whole cloth.” They relented, so I got to see pictures of devices and sets. For example, the descriptions of Maz Kanata’s cantina in the book reflects the images I saw, some of which were completed and some that weren’t.

Ele não falou com Jar Jar Abrams durante a escrita do livro, nem sequer uma vez.

Did you have any direct contact with J.J. Abrams during the process?

No, I’ve never met J.J. and vice versa. Doing a small film is a 24/7 project, and a film like this more like a 25/7 job. I’ve been on sets with directors making nine figure-plus films and you’re lucky if you can get a midnight meeting with them while they’re eating dinner…. I’m sure we’ll bump into each other one of these days, and talk about anything other than Star Trek and Star Wars.

Have you seen any of the movie, or did you work from the screenplay alone in writing the novelisation?

ALAN DEAN FOSTER: Just the screenplay, plus some concept art and production visuals. I really wanted to have access to the latter so that if I describe something, or someone, in the book, it matches what actually appears on the screen. You know how fans are. If I give someone sideburns and in the film that character appears without them, it will give rise to 468 blog entries.
