Halo

Halo (also known as Halo: The Series) is an American military science fiction television series developed by Kyle Killen and Steven Kane for the streaming service Paramount+, based on the video game franchise of the same name. Produced by Showtime Networks, 343 Industries, Amblin Television, One Big Picture, and Chapter Eleven, the series follows a 26th-century war between the United Nations Space Command and the Covenant, a theocratic-military alliance of several advanced alien races determined to eradicate the human race.

Pablo Schreiber and Jen Taylor star as Master Chief Petty Officer John-117 and Cortana, with the latter reprising her role from the video game series, and are joined by Shabana Azmi, Natasha Culzac, Olive Gray, Yerin Ha, Bentley Kalu, Kate Kennedy, Charlie Murphy, Danny Sapani, Bokeem Woodbine, and Natascha McElhone. Development for a television series began in 2013. Killen was hired in June 2018, and the series officially announced a nine-episode order for Paramount+. Filming began in Ontario, Canada in October 2019, although post-production for the first five episodes was affected due to the COVID-19 pandemic. Filming eventually resumed in Budapest, Hungary, in February 2021.

Halo premiered on March 24, 2022, on Paramount+, with the series already renewed for a second season. The first season was met with mixed reviews, with praise aimed towards its action scenes, cast, and visual effects but criticism for its derivative writing and alterations from the source material.
