The CW has greenlit its first new series for the 2015-16 season — in a big way.

The network has picked up “The Flash” and “Arrow” spinoff “DC’s Legends of Tomorrow” and ordered “Crazy Ex-Girlfriend,” the comedy pilot Showtime passed on. Plus, Julie Plec is getting another series on CW’s slate: “Cordon.”

“DC’s Legends of Tomorrow” is a mashup of DC legends starring a team of “The Flash” and “Arrow” characters. Time-traveling rogue Rip Hunter (played by Arthur Darvill) is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat — one in which not only the planet is at stake but all of time itself. Along with Darvill, Victor Garber (“The Flash”), Brandon Routh (“Arrow”), Caity Lotz (“Arrow”), Ciarra Renee and Franz Drameh star, alongside Dominic Purcell (“The Flash”) and Wentworth Miller (“The Flash”). The series hails from Bonanza Productions, Berlanti Productions and Warner Bros. TV with Berlanti, Marc Guggenheim, Andrew Kreisberg and Sarah Schechter exec producing.

“Crazy Ex-Girlfriend” stars comedian Rachel Bloom as a successful, driven and possibly crazy young woman who impulsively gives up everything — her partnership at a law firm and her upscale Manhattan apartment — in a desperate attempt to find love and happiness in that exotic hotbed of romance and adventure, West Covina, Calif. Showtime originally ordered the pilot, and then passed on the project, leaving the CW available to swoop up the CBS Studios production. Bloom will also exec produce with “The Devil Wears Prada” scribe Aline Brosh McKenna and Marc Webb of “The Amazing Spider-Man” films.

“Cordon” marks the third series on the CW for “Vampire Diaries” and “Originals” showrunner Plec. Based on a Belgian series, the dark drama revolves around an epidemic that breaks out in Atlanta, leaving some people stuck on the outside of a large city quarantine. The cast includes “Vampire Diaries” and “Carrie Diaries” alum Chris Wood, David Gyasi, Christina Moses, Kristen Gutoskie, Claudia Black, George Young, Hanna Mangan Lawrence and Trevor St. John. My So-Called Company and Warner Bros. TV will produce with Plec exec producing with David Nutter (The Flash,” “Arrow”).
