Snyder was the director of Justice League during principal photography, but was replaced by Joss Whedon during post-production. Snyder retained directorial credit for the finished film, though reports have indicated Whedon reshot a significant portion of the film. Snyder later edited a director's cut of the film, removing all of Whedon's footage and restoring his own footage that was deleted in the theatrical release. Snyder also shot four to five minutes of additional footage in late 2020 for his cut, released as Zack Snyder's Justice League.[2][3][4]
