The Euphoria cast and crew have mourned the deaths of some of their colleagues over the years. Euphoria, which premiered in 2019, originally followed troubled high school student Rue (Zendaya) as she struggled to remain sober after rehab. The hit HBO series was quickly renewed for a second season after its premiere, but it took nearly three years for the next batch of episodes to air. Season 3 was originally set to air on HBO in 2025 before facing several obstacles, including creator Sam Levinson's commitment to his short-lived series The Idol.
