In March 2015, it was announced that Ben Mendelsohn had been cast in a lead role in Rogue One. The scene was cut as writers had trouble justifying why Krennic would have survived the explosion the Death Star caused. Earlier planned endings for the film featured Krennic surviving the events on Scarif before being killed by Darth Vader for not preventing the theft of the plans to the Death Star. In Knoll's original story draft of the film, Krennic was a double agent on Jyn Erso's team reporting to the Imperial Security Bureau, however this was changed when Gary Whitta came aboard to write the script. Hearing about the development of a live-action Star Wars television series, he conceived a story, inspired by a plot point mentioned in the opening crawl of the original 1977 film Star Wars, which would eventually become Rogue One. Industrial Light & Magic chief creative officer John Knoll, credited for the story of Rogue One, told Vanity Fair in 2016 that he conceived the plot of the film while working as a visual effects supervisor on the 2005 film Star Wars: Episode III – Revenge of the Sith.
