Matthew McConaughey Takes Legal Steps Against AI Misuse by Trademarking His Voice and Catchphrases
Hollywood star Matthew McConaughey has taken a proactive and legal approach to prevent unauthorized use of his voice, catchphrases and likeness by artificial intelligence systems by registering multiple trademarks in the United States. The move comes amid increasing industry-wide debate about how generative AI can create fake audio, video or digital impersonations that mimic real actors’ voices and images without consent.
Among the trademarks McConaughey secured is a sound mark for his iconic line “Alright, alright, alright,” which he first delivered in the 1993 film Dazed and Confused. This phrase has since become widely associated with him and is one of the best-known catchphrases in modern film culture. In addition to the catchphrase, McConaughey’s legal team has registered a series of other trademarks connected to his voice and appearance, including short audio and video clips.
The actor’s lawyers, working with a specialised entertainment law firm, filed eight trademark applications with the United States Patent and Trademark Office, several of which were granted in late 2025 and early 2026. These registrations are designed to give McConaughey legal recourse to challenge unauthorized use of his identity in AI-generated content. While there have been no specific reports of his voice or image being misused by AI so far, the actor and his team have said they wanted to establish clear legal boundaries ahead of time.
