Unfortunately, Gomez-Rejon did not get to read the original book to The Current War: Director’s Cut’s more stage-ready counterpart, but he did head into the movie with a sort of simpatico sort of mindset when it came to how music meshed with the film.
As you can see above, not everyone involved with The Current War: Director’s Cut was in the dark about the musical roots to this very idea, as director Alfonso Gomez-Rejon not only knew of the original form this story too, but he got to hear songs from it as well!
