Good Mourning was theatrically released on May 20, 2022, through Open Road Films. The film received mainly negative reviews from critics, and its box office was negatively impacted at the time of the release. It was nominated for 43rd Golden Raspberry Awards, winning Worst Director for Baker and Mod Sun.
