The ghost of The Karate Kid‘s superior sensei, Mr. Miyagi, loomed large in the newest Cobra Kai season, which is igniting all sorts of feelings for the beloved character and the man who portrayed him, Pat Morita. The legend himself is now getting the deep-dive treatment in a new documentary, More Than Miyagi, and the above trailer is … a lot. From his early childhood battle with debilitating spinal tuberculosis to his struggles with substance abuse, this movie promises to keep the emotions running high with interviews and anecdotes not only from Ralph Macchio, William Zabka, and Martin Kove but also Happy Days co-star Henry Winkler and others who supply memories from Morita’s stand-up comedy days, including another legend you may have heard of, Tommy Chong.
