Katherine Waterston (Fantastic Beasts And Where To Find Them) is set to play the female lead in The Current War.
The film shows the struggle between Edison and Westinghouse over the supply of electricity. Edison championed the use of a direct current for electric power distribution over an alternating current, which was backed by several European companies and Westinghouse Electric.
Edison will be played by Beneduct Cumberbatch and Westinghouse by Michael Shannon. Alfonso Gomez-Rejon (Me and Earl and the Dying Girl) will direct the film.
Waterston will next be seen in Fantastic Beasts and Where To Find Them and Logan Lucky
