Keto Shimizu

Keto Shimizu (born December 23, 1984) is an American television writer, producer, and comic book writer.
She is well known for her work on the North American adaptation of Being Human; and for her substantial contributions to Greg Berlanti's and The CW's Arrowverse.

The daughter of an Asian Art Historian father and one of the founders of the first Waldorf school in Princeton, New Jersey mother, Shimizu accredits her love for storytelling to Waldorf teachings. She graduated from Twinfield High School in Plainfield, VT, and Emerson College in Boston. Shimizu and her husband, Christopher Lastrapes, have one child together.

She is an emphatic Batman fanatic, and attributes comic book and television writer Paul Dini as being a notable favorite interpreter. She also counts John Ostrander, Alan Moore, Kurt Buslek, Frank Miller and Chris Claremont as being influential to her writing.

Her first foray into film was with the western short Razor Man, which she wrote and directed, in 2006. The film depicts a lone gunslinger's quest for vengeance in rural 1891 Colorado. In 2007, she directed and wrote a second short film entitled Threads.

She has worked a vast array of positions in her career including post-production assistant (The Spirit, Tron: Legacy), visual effects editorial coordinator (Clash of the Titans), cinematographer (short film The Storm), and camera operator/first assistant to camera (web series Downers Grove).

She worked as a staff writer on the short-lived NBC series The Cape.

Being Human

In 2012, she joined the Syfy adaptation of Being Human, as a story editor. She went on to become a writer on the show, scripting three hours ("Dream Reaper", "I'm So Lonesome I Could Die", "Of Mice and Wolfman") of the paranormal drama.

Arrow, The Flash, Vixen and DC's Legends of Tomorrow

In the summer of 2013, Shimizu boarded the DC Comics produced Green Arrow origin series Arrow, as an executive story editor and writer. Her first episode she co-wrote, with executive producer Marc Guggenheim, was "Broken Dolls", which was critically lauded. Other sophomore season episodes she contributed to include "Blast Radius", "Suicide Squad" and "The Man Under the Hood".

On July 9, 2014, it was reported that a prequel comic book series would debut in September of that year to bridge the second and third seasons of Arrow, written by Shimizu and Guggenheim, entitled Arrow 2.5. Some of her work emphasizes the characters she established, with Bryan Q. Miller, in her Suicide Squad episode.

With the commencement of the series' third season, Shimizu was promoted to co-producer, along with Ben Sokolowski. She and co-executive producer Jake Coburn co-wrote the season's second installment, "Sara". She co-wrote the sixth episode, "Guilty", with co-executive producer Erik Oleson. She and Coburn co-penned the season's mid-season finale "The Climb", which fully introduced supervillain Ra's al Ghul (Matt Nable). Shimizu scripted her first solo outing with "Suicidal Tendencies", helmed by Jesse Warn. It saw the reformation of Task Force-X, with new member Cupid/Carrie Cutter; and explored the past of Deadshot.

Shimizu co-wrote, with Sokolowski, the fourteenth episode, "Fallout", of Arrow's sister-series The Flash. It showcased the DC superhero Firestorm (Robbie Amell/Victor Garber) and featured the first spoken words of supervillain Gorilla Grodd.

During the 2015 Winter Television Critics Association tour, The CW announced a new 6-part animated series, Vixen, centered around the DC heroine. It premiered on CW Seed in August of the year, and was released weekly on Tuesdays. It shares the same universe as Arrow and The Flash. The series is written by Shimizu, Arrow showrunner Wendy Mericle, Brian Ford Sullivan, and comic book writer Lauren Certo.

At the start of production for Arrow's fourth season, Shimizu was promoted once again; being named producer, along with Sokolowski. She co-scripted the second episode of the season "The Candidate" with Guggenheim; which saw the introduction of supervillain Anarky. She and new co-executive producer Speed Weed wrote the seventh episode "Brotherhood". Shimizu next contributed to the 13th episode "Sins of the Father" with Sokolowski; and the 15th episode "Taken", which she and Sullivan wrote a teleplay for, based on a story from Guggenheim; and the critically panned "Eleven-Fifty-Nine", co-written with Guggenheim.

With the conclusion of a poorly received fourth season of Arrow, Shimizu announced that she would be departing the series, and relocating to spin-off DC's Legends of Tomorrow. She will function as a writer, for the ragtag time-traveling show's sophomore series; which will give her the opportunity to write for members of the joining Justice Society of America.
