Overview

• The estate of Superman co-creator Joseph Shuster has filed a lawsuit against Warner Bros. Discovery, citing copyright reversion laws in Canada, the UK, Ireland, and Australia.
• The lawsuit alleges that Shuster's foreign copyrights automatically reverted to his estate 25 years after his death in 1992, under laws in countries with British legal traditions.
• The estate seeks damages, a share of profits from prior works, and a court order to block the release of the new Superman film in the affected territories without proper authorization.
• Warner Bros. disputes the claims, asserting that it retains the rights to the character and plans to defend its position vigorously in court.
• James Gunn's Superman film, set for release on July 11, 2025, is intended to launch a new DC cinematic universe, raising the stakes for resolving the legal dispute.
