James Gunn Debunks Superman: Legacy Rumor, Teases Further Casting Announcements

James Gunn has debunked a rumor regarding his upcoming Superman: Legacy movie.

On November 19, 2023, Gunn shared an Instagram post showing off the wall in his production office, which is covered in artwork from Superman for All Seasons, a 1998 comic book series written by Jeeps Loeb and illustrated by Tim Sale.

Two days prior to Gunn’s Instagram post, Twitter user @ViewerAnon tweeted, “Heard some stuff about SUPERMAN: LEGACY. I trust the source but this stuff is always fuzzy. Superman’s early in his career and isn’t widely known. His big public reveal happens in the Middle East, where terrorists have gotten ahold of Kryptonian tech.

“Waller and Sam Lane send in the Authority to investigate – they believe Superman is responsible. Superman learned of the tech in the Fortress of Solitude and hopes it will be the missing puzzle piece to discover where he comes from. Anyway, the big bad is Brainiac behind everything. As said in the first post, I trust the source but it’s all a game of telephone with info passed ear to ear, so we’ll see how much of this (if anything) pans out. Sounds solid to me though if it’s true.”

When asked if the storyline rumor was true in the comments to his Instagram post, Gunn responded, “It isn’t true.”
