Input: Question: Which of the actors as Thomas Edison and George Westinghouse as of September 24, 2015 is older? Passage:Michael Mitnick began writing the script for The Current War in 2008, basing it on the real life "war of the currents" AC/DC conflict between Edison and Westinghouse. The screenplay is the conclusive result of sixty drafts, a ten-year writing process, first as a musical and finally as a film. In 2011 Mitnick's screenplay made the Black List, an industry survey of "most liked" screenplays not yet produced. On May 3, 2012, it was reported that Timur Bekmambetov's company, Bazelevs, had acquired the rights to Mitnick's screenplay. Bekmambetov was set to direct. On March 31, 2014, it was reported that Ben Stiller was in negotiations to direct the film. As of September 24, 2015, Benedict Cumberbatch and Jake Gyllenhaal were in talks to play Thomas Edison and George Westinghouse, respectively, with Alfonso Gomez-Rejon (Me and Earl and the Dying Girl) eyed to direct the film. Sacha Baron Cohen was also briefly linked to the role of Edison. On September 29, 2016, Michael Shannon was cast as Westinghouse, and on October 4, Nicholas Hoult was cast as Nikola Tesla. In November 2016, Katherine Waterston and Tom Holland joined the cast. The following month, Tuppence Middleton and Matthew Macfadyen were cast.
