The Arrowverse is an American superhero media franchise and shared universe that is centered on various interconnected television series based on DC Comics superhero characters, primarily airing on The CW as well as web series on CW Seed. The series were developed by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Geoff Johns, Ali Adler, Phil Klemmer, Salim Akil, and Caroline Dries. Set in a shared fictional multiverse much like the DC Universe and DC Multiverse in comic books, it was established by crossing over common plot elements, settings, cast and characters that span six live-action television series and two animated series.

The franchise began with Arrow, based on the character Green Arrow, which debuted in October 2012. It was followed by The Flash in 2014, and the animated web series Vixen in 2015. The franchise further expanded in January 2016 with the debut of Legends of Tomorrow, starring characters who previously appeared on both Arrow and The Flash. Later that year, the CBS series Supergirl, having already crossed over with The Flash, moved to The CW for the remainder of its run. A second animated web series, Freedom Fighters: The Ray, was released in 2017, which followed Ray Terrill / The Ray, who would make a live-action appearance during that year's crossover event "Crisis on Earth-X". In addition to the live-action and web-based series, the franchise has spawned three promotional tie-in live-action web series: Blood Rush, Chronicles of Cisco and The Flash: Stretched Scenes; released in 2013, 2016 and 2017 respectively. A fifth series, Batwoman, premiered in 2019. Six ensemble crossover events involving many of the live-action series of the Arrowverse have taken place, beginning with "Flash vs. Arrow" in 2014 and concluding with "Crisis on Infinite Earths" between 2019 and 2020. Additionally, Matt Ryan has reprised his role as John Constantine from the NBC series Constantine, initially in guest appearances in episodes of Arrow and Legends of Tomorrow, before becoming a series regular for the latter, in addition to continuing storylines from the former series. In 2023, the franchise concluded with the ninth and final season of The Flash.

Based on the DC Comics character created by Otto Binder and Al Plastino, the series follows Kara Zor-El (played by Melissa Benoist), Superman's cousin, and one of the last surviving Kryptonians from the planet Krypton. As Supergirl, Kara uses her powers to protect National City. The series was retroactively incorporated into the Arrowverse beginning with its second season, and became definitively linked with the rest of the franchise in the fifth season.

The series was officially picked up on May 6, 2015, after receiving a full series commitment in September 2014. Following a full season order on November 30, 2015, it transitioned to The CW for its second season going forward.

Superman & Lois is an American superhero drama television series developed for The CW by Todd Helbing and Greg Berlanti, based on the DC Comics characters Superman and Lois Lane, created by Jerry Siegel and Joe Shuster. Tyler Hoechlin and Elizabeth Tulloch star as the title characters Clark Kent / Superman and Lois Lane, respectively. Jordan Elsass and Alex Garfin portray the couple's twin sons Jonathan and Jordan Kent, with Michael Bishop replacing the former in the third season. The series also stars Erik Valdez, Inde Navarrette, Wolé Parks, Adam Rayner, Dylan Walsh, Emmanuelle Chriqui, Tayler Buck, Sofia Hasmik, Chad L. Coleman, and Michael Cudlitz.

The series was originally part of the Arrowverse's Earth-Prime in its first season, developed as a spin-off of Supergirl, with Hoechlin and Tulloch respectively reprising their roles from Supergirl and The Flash, and the conclusion of the "Crisis on Infinite Earths" crossover event serving as a backdoor pilot. As the series went on, following the cancellation of planned crossovers with Supergirl and Batwoman due to the COVID-19 pandemic, showrunner Todd Helbing and Warner Bros. decided to keep the show separate, with the series instead set in its own separate continuity; taking place on a different Earth to Earth-Prime, which was confirmed in the second season finale.

He is given a ring that grants him superpowers and must confront Parallax, a being who threatens to upset the balance of power in the universe. The film also stars Blake Lively, Peter Sarsgaard, Mark Strong, Angela Bassett, and Tim Robbins.

The film first entered development in 1997; progress remained stalled until Berlanti was hired to write and direct in October 2007. Martin Campbell was brought on board in February 2009 after Berlanti was forced to vacate the director's position. Most of the live-action actors were cast between July 2009 and February 2010, and filming took place from March to August 2010 in Louisiana. The film was converted to 3D during its post-production stage. This was the first DC film since Catwoman (2004) not to be involved with Legendary Pictures.
