Supergirl screenwriter Ana Nogueira says she struggled to get to grips with the often cheerful and optimistic portrayals of Kara Zor-El until she encountered Tom King's comic book Woman of Tomorrow. "I was always like, 'I can’t get my head around the version of the character that is so sunny,'" she added. That was, until she encountered King’s "rougher and grittier and edgier and funnier" version of Kara in Woman of Tomorrow, on which her script is based. Supergirl is Nogueira's first feature film, but she's already working on Wonder Woman and Teen Titans movies for James Gunn's DC Studios, too.
