Matthew McConaughey is officially drawing a legal line in the sand — and it’s aimed straight at AI impostors. The star has trademarked his legendary catchphrase “All right, all right, all right,” along with several short audio and video clips tied directly to his likeness. The move is designed to block AI-generated knockoffs that copy his voice, image, or vibe without permission. The trademark — approved by the U.S. Patent and Trademark Office — is classified as a sound mark, down to the exact pitch and rhythm of McConaughey’s delivery. His legal team says this goes beyond traditional celebrity protections. While right-of-publicity laws already exist, trademarks give McConaughey a clear path to federal court, even if the AI content isn’t being used to sell anything. Ironically, McConaughey isn’t anti-AI. He’s already partnered with ElevenLabs to replicate his own voice for a Spanish version of his Lyrics of Livin’ newsletter. The point isn’t stopping AI — it’s stopping unauthorized AI. All eight trademarks are registered under his company, J.K. Livin Brands, which also runs his apparel business. The catchphrase itself was famously improvised in Dazed and Confused back in 1993 — a line he never expected to define his career.
