In the brutal future of Frank Herbert’s Dune, computers are outlawed and high
level computations are done by specially trained and bred humans called
mentats. In Herbert’s world, there’s something elegant about old solutions to
new problems. Good then that Oscar winning Dune screenwriter Eric Roth banged
out the screenplay using the MS-DOS program Movie Master[1].

Roth writes everything using the 30-year-old software. “I work on an old
computer program that’s not in existence anymore,” Roth said in an
interview[2] in 2014. “It’s half superstition and half fear of change.” Roth
wrote the screenplay for Dune in 2018 and explained he was still using Movie
Master on a Barstool Sports podcast[3] in 2020. That means Dune was written in
an MS-DOS program.

There’s really no reason to stop using software that you like, assuming you can
make it secure and ensure your work is properly backed up. It’s trivial to set
up a DOS environment, and it’s trivial to ensure not just the files you’re
working on, but the entire DOS environment itself is backed up. This applies to
many old and outdated platforms – there’s countless ways to virtualise, or to go
on eBay and buy some original hardware.
