Why 'Zack Snyder's Justice League' ends on the song 'Hallelujah'

• "Zack Snyder's Justice League" ends with the song "Hallelujah" and the words "for Autumn."
• The movie is dedicated to Snyder's late daughter Autumn, who died by suicide in 2017.
• "Hallelujah" was Autumn's favorite song, and Canadian singer Allison Crowe covered it for the movie.

"Zack Snyder's Justice League" ends with a cover of Leonard Cohen's "Hallelujah" with the words "For Autumn" displayed at the end of the film.

It's a tribute to Snyder's daughter, Autumn. Autumn died by suicide at the age of 20 in 2017, which is why Snyder and his wife Deborah, who produced the "Snyder Cut," originally stepped away from "Justice League."

The "Snyder Cut" is dedicated to Autumn and "Hallelujah" was chosen for the end credits because it was her favorite song.

The song is covered by Canadian singer and songwriter Allison Crowe, who also performed it at Autumn's funeral in 2017 as well. Crowe then recorded a new version of the song specifically for the "Snyder Cut." She first covered the song in 2005.

This is not the first time Snyder has used "Hallelujah" in his movies. He used the original Leonard Cohen version in his 2009 movie "Watchmen," although Crowe recently told Billboard reporter Gab Ginsberg that he approached her about using her cover of the song for that movie.

In the same interview, Crowe, who also appeared as a singer in a bar in "Man of Steel," told Billboard that while she never met Autumn, she did know how much the song meant to her.

"This whole project really is a tribute to Autumn, and to the family. It's so beautiful," Crowe said. "I just know that they've been through so much - I'm gonna get emotional - and that they are such incredible people. He did let me know how much it means."

In a recent interview with Vanity Fair reporter Anthony Breznican, Snyder said that the "Snyder Cut" "absolutely would not have happened" if it weren't for Autumn. Snyder said that Autumn was a writer and that she used her characters as a way to cope with her pain.

"Her main characters are always in this battle with things from another dimension that no one can see," Snyder told Breznican. "But it's a serious war. And that war was happening to her every day. I think so many people are in that battle, and they smile and nod at you."

There are no mid- or post-credits scenes in the "Snyder Cut," although the movie does end on a cliffhanger that could tease potential sequels. There are also characters introduced that would be ripe for sequels, too, although none have been planned as of yet.
