Last week, we reported that The Vampire Diaries and The Originals star Claire Holt is one of several actresses who tested for the title role of CBS' Supergirl. However, The Hollywood Reporter is now reporting that the actress isn't expected to win the role. It still isn't known what other actresses are currently reading to play Kara Zor-El.

The project already has a series commitment from CBS, which was issued just a few weeks after the project was first announced back in September. The story will center on a 24-year-old Kara Zor-El, who has been living on Earth for several years after escaping just before her home planet of Krypton was destroyed. While she has refused to use her incredible powers throughout her life, Kara decides to embrace her gifts and become the hero she was always destined to be. Last month we reported that series co-creator Greg Berlanti and Colleen Atwood were going over Supergirl's costume, but it isn't known if her new look is finalized quite yet.

Greg Berlanti, who executive produces Arrow and The Flash, co-wrote the pilot script with former No Ordinary Family collaborator Ali Adler. Both writers will serve as executive producers on Supergirl alongside Sarah Schechter. We reported last month that Supergirl may cross over with Arrow and The Flash, despite airing on different networks, but those plans have not been confirmed. No production schedule was given for the Supergirl pilot, and it isn't known when CBS plans on airing the series at this time.
