The Flash 2014

The Flash is an American superhero television series developed by Greg Berlanti, Andrew Kreisberg, and Geoff Johns, airing on The CW. It is based on the Barry Allen incarnation of DC Comics character the Flash, a costumed superhero crime-fighter with the power to move at superhuman speeds. It is a spin-off of Arrow, existing in the same fictional universe known as the Arrowverse. The series premiered in the United States on The CW on October 7, 2014, and ran for nine seasons until May 24, 2023. The series follows Barry Allen, portrayed by Grant Gustin, a crime scene investigator who gains super-human speed, which he uses to fight criminals, along with others who have also gained superhuman abilities. Initially envisioned as a backdoor pilot, the positive reception Gustin received during two appearances as Barry on Arrow led to executives choosing to develop a full pilot to make use of a larger budget and help flesh out Barry's world in more detail. The series is primarily filmed in Vancouver, British Columbia, Canada. The Flash's premiere on October 7, 2014 became the second-most watched pilot in the history of The CW, after The Vampire Diaries in 2009.
