The case of Onoda, a WW2 Japanese soldier who carried on fighting for thirty years on the Philippine island of Lubang before being persuaded to give up, was a celebrated case in the mid 1970s, and I was really impressed by this dramatic reconstruction of his life. It's a high quality movie, beautifully filmed, thoughtful, and well played all round, though I also thought it a bit too long at more than 2.5 hours. There are great performances all round and solid direction which almost has a David Lean approach at times (no bad thing), so it's a 'small scale epic' with a heart, and well worth a view. There are some supremely effective moments, and the film deserves a wider audience, though you do have spare quite a bit of time.
