CBS has entered the world of comic book television series, ordering a full series about Superman's cousin Supergirl, and without a pilot episode.

Unusual in picking up a new television series, CBS has completely bypassed the "in development" and "pilot" stages, committing to the series before anyone has even been officially cast.  'Supergirl' is currently slated to be a one-hour drama from Berlanti Productions, the same team behind CW's 'Arrow' and 'The Flash', while Greg Berlanti and Ali Arder ('Chuck') will serve as writers and Executive Producers.  Crossovers between the other DC comic television shows seems unlikely with 'Arrow' and 'The Flash' being on the CW and 'Gotham' airing on FOX (also, 'Gotham' will be taking place long before the events that would include Supergirl).

Supergirl has been a mainstay of DC comics for many years, having different origins each time she's introduced.  Currently, Supergirl is Superman's teenage cousin, Kara Zor-El, who was sent from Krypton before it blew up to track down her then-younger cousin Kal-El and kill him.  With her ship being knocked off course, Kara didn't arrive on Earth until 30 years after Kal-El landed.  According to IGN, the series will focus on a 24-year-old Kara finally embracing her abilities which she's kept hidden, and becoming a superhero.

This will not be the first time Supergirl has appeared in a live-action adaptation.  Helen Slater appeared as Kara in the 1984 film 'Supergirl', intended to be a spin-off of the Christopher Reeve films.  Laura Vandervoort played the current incarnation of Kara in 'Smallville', but never appeared in the iconic suit.
