In March 18, 2021, after almost four years of online petition and fan pressure, Warner Bros. released the original director's cut of Justice League, renamed Zack Snyder's Justice League. The cut was more than two hours longer than the theatrical version, including additional scenes, alternate takes, detailed expositions, more character backstory and even a different camera setup and musical score by Junkie XL. Also, the new version introduced characters that were cut from the theatrical version like Iris West (Kiersey Clemons), Antiope (Robin Wright), Ares (David Thewlis), King Arthur (Francis Mcgee) Martian Manhunter (Harry Lennix), DeSaad (Peter Guinness), Cyborg's mother Elinore (Karen Bryson), Ryan Choi (Zheng Kai) and Justice League's archenemy, Darkseid (Ray Porter). The cut was rated R for violence and language, unlike the theatrical version, which was PG-13.
