After the release of the film, director David Gordon Green announced an extended cut which would feature additional scenes and an alternate ending. In that cut (simply titled Extended Cut), Laurie would call Karen's phone near the end of the film. She is instead replied with Michael's heavy breathing, indicating Karen is dead. Laurie then leaves the hospital with a knife, determined to find him. This indicates the sequel Halloween Ends (2022) would take place immediately after Kills in 2018, instead of four years later in 2022 which would later be confirmed. The Extended Cut runs for 109 minutes.
