9-1-1 is an American procedural drama television series created by Ryan Murphy, Brad Falchuk, and Tim Minear.

The series currently stars Angela Bassett, Peter Krause, Oliver Stark, Jennifer Love Hewitt, Ryan Guzman, Aisha Hinds, Kenneth Choi and Gavin McHugh.

[23] Later that month, it was announced that Oliver Stark, Aisha Hinds, Kenneth Choi, and Rockmond Dunbar had been cast in regular roles.

[35] On May 14, 2018, it was announced that Jennifer Love Hewitt would join the main cast as Maddie Buckley, Buck's sister, in season 2, replacing the role of Britton's character Abby Clark.

In season 5, Dunbar departed over the COVID-19 vaccine mandate implemented by 20th Television after his requests for medical and religious exemptions were denied.

The website's critical consensus reads, "9-1-1 occasionally veers into melodrama, but is redeemed with a top-tier cast, adrenaline-pumping action, and a dash of trashy camp that pushes the show into addictive guilty pleasure territory.

[43] Steve Greene of IndieWire called 9-1-1 a perfect hit, stating the show manages to feel realistic and emotional across its dialogues and the relationships between the characters, applauded the action sequences with the different disasters, and praised the performances of the cast.

[44] Daniel Fienberg of The Hollywood Reporter found the series to be a conventional yet solid procedural drama, comparing it to the Chicago franchise, and applauded the performances of the cast, while calling the characters decent.

[41] Brian Grubb of Uproxx stated the second season of the series manages to be more ambitious than the first one, applauding the disasters and action sequences, and praised the performances of the cast and the development of the characters.

This marked the best multiplatform viewership for the show since April and made it the top broadcast TV drama among adults 18-49 for the season with an average live-plus-seven-day rating of 0.83.

[90] In September, Liv Tyler,[91] Ronen Rubinstein, Sierra McClain,[92] Jim Parrack,[93] Natacha Karam, Brian Michael Smith, Julian Works, and Rafael L. Silva[94] were also announced to star in the series alongside Lowe.

[96] On October 1, 2024, shortly after it was confirmed that 9-1-1: Lone Star's fifth season would be its last, Ryan Murphy revealed to Variety that a second 9-1-1 spinoff was in the works for ABC.
