I just stumbled across it on youtube, to be honest. I linked the remake of the Karate Kid film and, a click here, and a click there, and I ended up watching, somewhat fascinated. It's actually a bit surprising, because I don't really know anything about Morita (who died in 2005) and I don't really remember him out of that many films. Moreso, the production values are pretty bad, in that the interview can hardly be made out, and the camera has been basically dropped in front of Mortia's face. Perhaps even more daunting is that there are seven parts and each of chapter runs around 30 minutes.
Yet, yet, Morita is compelling, very assured, very confident, and with an interesting take of his life, so far. His memories of growing up in a hospital with spinal TB that, when he was well enough to walk, some nine years later, saw him escorted by an FBI agent to an internment camp as WW2 broke out are particularly fascinating.
