Despite the premiere's cancellation in the United States, the series had already been sold in international markets where it went on to debut as previously scheduled in its original ten-episode version. It aired for the first time on July 11, 2018, on
HBO Europe in select European territories.
On October 4, 2018, it was announced that the series would premiere in United States on October 25, 2018, on Paramount Network over the course of five nights. The series was
edited for content by the network resulting in numerous cuts and the number of episodes being
reduced from 10 to nine, with the original final two episodes being combined into one.
Despite reports by the writers that a second season,
Heathers: Revolution, had a complete script, Paramount Network's president
Kent Alterman announced in an interview on May 1, 2019, that there were no plans to continue
Heathers following its first and only season.
