Halo is an American military science fiction television series developed by Kyle Killen and Steven Kane for the streaming service Paramount+, loosely 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. Development for a Halo television series began in 2013. Showrunner Killen was hired in June 2018, and the series officially announced a 9-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.
