HBO's Green Lantern has not yet been renewed for a second season, but it has not been officially cancelled either. The show's creators refuted claims that Season 2 would not move forward, stating that currently, "nothing has been cancelled."
These rumors emerged after James Gunn and Peter Safran were removed from their positions as heads of DC Studios. Variety initially reported that the series, centered on the Green Lantern duo, would not be renewed.
Warner Bros. later corrected this statement, clarifying that the show's exact status is "not yet renewed." Therefore, at this stage, it can only be confirmed that a renewal decision has not been announced, and this should not be taken as evidence that Season 2 has been approved or officially cancelled.
