NBC’s Constantine, which is the fourth DC Comics property to be aired on TV, has endured some serious changes in the months prior to its premiere. After getting ordered to series in July, David Goyer and Daniel Cerone, executive producers of the show, announced that Angelica Celaya would be replacing Lucy Griffiths as the show’s female lead. Celaya will be seen portraying Zed, a foil for occult detective John Constantine, The Hollywood Reporter has learned.

“We wanted a more dynamic relationship, as opposed to someone who is a teacher/mentor and a student,” explained Cerone back in July. “It just didn’t feel as fertile and rich of an area as just a strong man and a strong woman who are both very different.” It’s those drastic shifts that can threaten to derail a show, but Welsh actor Matt Ryan (Criminal Minds), who dons the trench coat as the titular character, isn’t rattled by the changes, according to The Hollywood Reporter.
