With leaks and spoilers so prevalent in not just the Star Wars community but in every corner of every genre it’s a minor miracle that there were no major script leaks during the production of The Last Jedi.
There’s a good reason for that. Speaking with the Wall Street Journal, director and writer Rian Johnson explained the tech he used to keep the script and plot as air-tight as possible.
I typed Episode VIII out on a MacBook Air. For security it was ‘air-gapped’ — never connected to the internet. I carried it around and used it for nothing except writing the script. I kept it in a safe at Pinewood Studios.
I think my producer was constantly horrified I would leave it in a coffee shop.
