Gregory "Greg" Berlanti is an American writer, producer, and film director. He is known for his work on television series such as, Riverdale, Chilling Adventures of Sabrina, the "CWverse" shows, and most recently, Stargirl.
Berlanti co-wrote and co-produced the DC Comics film Green Lantern, starring Ryan Reynolds as the titular character. As the film was neither critically nor financially successful, further planned releases were cancelled.
In May 2016, Berlanti discussed his involvement in a Booster Gold feature film that was currently in development, as producer and possibly as director as well. Zack Stentz was signed to the project as screenwriter. It is still in movie limbo.
In January 2012, it was announced that, along with Andrew Kreisberg and Marc Guggenheim, Berlanti would create, write, and produce a series for The CW based on Green Arrow called Arrow. The series premiered on October 10, 2012, and was picked up to full series in the same month.
On July 30, 2013, it was announced at the summer TCA tour that Berlanti, Kreisberg, and DC Comics CCO Geoff Johns would be introducing Barry Allen in the second season of Arrow, with the possibility of the character being spun off to his own series. Actor Grant Gusin was cast and made his debut in episode 8, "The Scientist". In November 2013, The CW officially ordered a pilot for The Flash, and in May 2014 the network picked the project up to series with a premiere scheduled for autumn of that year.
Legends of Tomorrow
On February 26, 2015, it was announced that Berlanti, along with Guggenheim and Kreisberg, would write and executive produce a spin-off series featuring The Atom, Captain Cold, Martin Stein, and The White Canary, for a potential 2016 premiere. The series was ultimately titled Legends of Tomorrow, and follows the ragtag team of heroes and villains as they travel through time and space on a mission to stop the devious immortal Vandal Savage. The series premiered on January 21, 2016.
On September 4, 2014, it was reported that Berlanti would executive produce a re-imagining of the origin of Supergirl, to be written by Ali Adler. Flash co-creator Geoff Johns was also involved with development. On September 19, 2014, it was reported that CBS had made a series commitment to Supergirl. It was also announced that Berlanti would co-write the first episode.
After its first season, the show moved from CBS to The CW, bringing all live-action CWverse shows together on one network. The show made history in 2018 for featuring the first live action transgender superhero when Nicole Maines was cast in a recurring role.
