Sentai Filmworks, LLC (or simply Sentai), is an American entertainment company owned by AMC Networks. Located in Houston, the company specializes in the dubbing and distribution of Japanese animation and Asian cinema. Its post-production arm is Sentai Studios. The company has its origins in A.D. Vision, which was founded in 1992 by video game fans John Ledford and Matt Greenfield. ADV collapsed due to low sales and eventually liquidated its assets in 2009. Ledford founded Sentai in 2008 and acquired the majority of ADV's titles. Sentai was then acquired by New York City-based AMC Networks in 2022 and became its subsidiary. Its offices are in the International District in Southwest Houston.
