The arrivals of 'Constantine,' 'The Flash' and 'Gotham' gave DC Comics a monopoly on superhero TV, but CBS' forthcoming 'Supergirl' series might be the strongest of them all. Find out what take on Kara Zor-El 'Supergirl' will bring to CBS, as well as what other roles are in the mix, and what Superman has to do with it!

Per TVLine, the first casting call for DC producer Greg Berlanti's 'Supergirl' fully incorporates the character's Kryptonian origins, as well as the "Danvers" surname imagined as the family who took her in, but it doesn't seem as if Clark Kent or his more famous alter-ego factor into it. The series is also looking to cast Kara's foster sister Alex, who skews more toward the scientific than her 'Super' counterpart:

For Kara Zor-El aka Kara Danvers, the show is eyeing Caucasian females, age 22 to 26, to play 24. As the series’ mythology goes, Kara at age 12 was sent from her dying home planet of Krypton to Earth, where she was taken in by the Danvers, a foster family who taught her to be careful with her extraordinary powers. After repressing said skills for more than a decade, Kara is forced to bust out her super moves in public during an unexpected disaster. Energized by her heroism for the first time in her life, she begins embracing her abilities in the name of helping the people of her city, earning herself a super moniker along the way. The other lead role currently being cast is that of 26-year-old Alexandra “Alex” Danvers, Kara’s gorgeous, brilliant, science-minded foster sister. Growing up, Alex was partly jealous of her sibling yet also fascinated by her abilities, prompting Alex to learn as much as she could about alien anthropology, sociology and culture. Today, Alex works for a secret government organization and, alongside her heroic sis, will face many challenges, both mundane and super.

Then again, here's how CBS originally described the 'Supergirl' TV series:

Based on the DC Comics character, the drama tells the story of Kara Zor-El, who was born on the planet Krypton, but escaped amid its destruction years ago. Since arriving on Earth, she’s been hiding the powers she shares with her famous cousin Superman. But now, at age 24, she decides to embrace her superhuman abilities and be the hero she was always meant to be.

'Arrow' producer Greg Berlanti and 'No Ordinary Family''s Ali Adler will write the script and executive produce the hourlong drama through Berlanti Productions' Warner Bros. Television-based banner, with Sarah Schecter also executive producing. As with DC’s approach to movies and TV thus far, the new 'Supergirl' series will likely establish its own independent continuity, outside of ‘Arrow’ and ‘The Flash,’ or the inevitable ‘Justice League‘ movie.

Well, what do you think? The series hasn't been given a formal series order just yet (only a series commitment), but does CBS' take on 'Supergirl' seem like an original take on the character? How would you want to see the DC drama handled?
