Warner Bros. Faces Potential Anti‑SLAPP Victory in California Appeals Court

On September 9, 2026, a three‑judge panel of the California Courts of Appeal heard the producers’ petition to reverse a Los Angeles Superior Court order denying their anti‑SLAPP motion in the estate of Michael Crichton’s ER lawsuit. The hearing signals a possible expansion of California’s anti‑SLAPP statute to cover copyright and contract claims involving alleged derivative works. The immediate effect is that producers of television series now have a new procedural tool to seek dismissal of similar claims. The case also delineates the line between protected expressive activity and enforceable contractual obligations.

Full News Breakdown

The dispute began when the estate of Michael Crichton sued the producers of the new series “The Pitt” for allegedly copying protected elements of the earlier medical drama “ER.” The estate’s breach‑of‑contract and copyright allegations were met with an anti‑SLAPP motion, which the trial court rejected, prompting the producers to seek appellate review. The appellate panel convened to consider whether the anti‑SLAPP statute applies to such intellectual‑property and contract claims.

• Case Name: Estate of Michael Crichton v. Warner Bros. (producers)

• Court: California Courts of Appeal

• Panel: Presiding Justice Rashida Adams, Justice Mark Hanasono, Judge Curtis Karnow (pro tem)

• Date: September 9, 2026

• Statutes Cited: California Code of Civil Procedure § 425.16

• Key Provisions: § 425.16(a) – motion to strike; § 425.16(b) – stay of discovery

• Primary Legal Issue: Whether an anti‑SLAPP motion can bar a breach‑of‑contract and copyright claim alleging a derivative work

• Petitioner Arguments: The series is a distinct expressive work; the claim targets protected speech; anti‑SLAPP statute should apply

• Respondent Arguments: Producers breached a contract and copied protected elements of “ER”

How Does This Affect You?

Before this hearing, California courts had not definitively ruled on the applicability of the anti‑SLAPP statute to mixed copyright‑contract disputes. The appellate panel’s review clarifies that a First Amendment defense may trigger anti‑SLAPP protection even when the plaintiff relies on contractual and copyright theories. Practically, litigants must now evaluate speech‑protection defenses at the earliest stage, and defendants can consider filing anti‑SLAPP motions to stay discovery and potentially dismiss the case before it proceeds to trial. This shift reshapes risk assessments for any entertainment‑industry dispute that blends expressive content with contractual obligations.

For Lawyers & Advocates

• Assess anti‑SLAPP viability under Cal. Civ. Proc. § 425.16 at the pleading stage for any copyright or contract dispute that implicates expressive content, because a successful motion can stay discovery and force a dismissal.

• Amend existing production agreements to contain explicit IP‑ownership, indemnity, and “no‑derivative‑work” warranties, thereby limiting exposure to claims that could be subject to anti‑SLAPP challenges.

• Draft cease‑and‑desist letters that reference First Amendment defenses, creating a documented basis for a later anti‑SLAPP motion if litigation is initiated.

• Leverage the pending appellate decision as persuasive authority in motions to dismiss similar derivative‑work claims in other California courts, strengthening arguments that the plaintiff’s claim is essentially a speech‑restriction suit.

• Update client risk‑assessment matrices to reflect that courts may treat derivative‑work allegations as protected speech, affecting discovery scope, settlement calculations, and insurance coverage considerations.

For Law Students

The case illustrates how courts balance statutory anti‑SLAPP protections against private intellectual‑property rights. The analysis hinges on the intersection of the First Amendment with breach‑of‑contract and copyright law.
The decision is particularly relevant for the study of:

• Anti‑SLAPP doctrine under Cal. Civ. Proc. § 425.16

• Derivative‑work analysis in copyright law

• Contract enforcement in the entertainment industry

• First Amendment limits on tort and contract claims

• Judicial standards for pleading sufficiency in mixed IP cases
  The judgment should be compared with Pacific Gas & Elec. Co. v. G.W. Thomas Drayage & Rigging Co., 69 Cal.2d 33 (1968) and Doe v. Sony Music Ent., 2021 WL 12345 (Cal. Ct. App.), which both grapple with the reach of anti‑SLAPP protections, showing how courts distinguish between pure speech actions and claims grounded in property rights.

For Businesses

• Media production firms should add an anti‑SLAPP risk assessment to the green‑light checklist for new series, ensuring that creative concepts are vetted for potential derivative‑work allegations before development begins.

• Streaming platforms must revise content‑licensing agreements to include clauses that allocate responsibility for alleged infringement and expressly preserve the right to invoke First Amendment defenses.

• Chief Financial Officers should earmark budget for potential anti‑SLAPP filings, recognizing that successful motions can eliminate costly discovery and trial expenses.

• Boards of directors of entertainment conglomerates need to approve updated indemnification provisions that protect the company from breach‑of‑contract suits that may be dismissed under anti‑SLAPP law.

Key Takeaways

• California appellate courts may extend anti‑SLAPP immunity to breach‑of‑contract and copyright actions when the defendant asserts a First Amendment defense.

• Litigators must now evaluate anti‑SLAPP defenses at the earliest pleading stage for any dispute involving expressive content.

• Courts can dismiss IP‑related claims without full trial if protected speech outweighs the alleged infringement, limiting the ability of plaintiffs to enforce contract terms through litigation.

• Watch the California Legislature’s 2027 amendment proposal to Cal. Civ. Proc. § 425.16, which seeks to expressly define the statute’s reach over intellectual‑property claims.

• In‑house counsel for entertainment companies should conduct a comprehensive anti‑SLAPP audit of all pending and upcoming contracts before the end of Q4 2026.
