The script of Dune was edited on the MS-DOS system, which is 30 years old.

Recently, a Vice reporter discovered that "Dune" screenwriter Eric Roth used a software called Movie Master to write the script of the film. This software is a 30-year-old MS-DOS program, which means that the "Dune" script was completed on the MS-DOS system and Roth actually created all his works in this software.

Screenwriter Eric Roth once mentioned in an interview: "Working on an old program that no longer exists on computers is half superstition and half fear of change."
