Warner Bros. Moves to Toss ‘Superman’ Suit Over Foreign Copyrights

Warner Bros. Discovery and DC Comics have moved to throw out a lawsuit over the copyrights to “Superman” in foreign territories, arguing the issue has already been exhaustively litigated.

Mark Peary, the nephew of the late Superman co-creator Joe Shuster, filed the suit in January, seeking to invalidate the studio’s copyrights under the laws of the United Kingdom, Canada, Australia and Ireland. If successful, the lawsuit could interfere with the release in July of “Superman,” starring David Corenswet and directed by James Gunn.

In response, Petrocelli argued that the Berne Convention is not enforceable in U.S. courts, and that the case should be dismissed because the court lacks jurisdiction.

The studio also argued that the Shuster estate’s claims have already been denied by a federal judge in Los Angeles, and those findings were upheld by the 9th Circuit Court of Appeal in 2013.

The studio also offered a summary of the many legal disputes that have arisen since Shuster and Jerome Siegel first signed away the rights to Superman for $130 in 1938. Since then, the studio argued, the creators and their heirs have received millions of dollars, adjusted for inflation, in royalties and other payments.

After Shuster died, his sister — and sole heir — asked…
