"Onada - 10,000 nights in the jungle". Based on the true story of the Japanese officer who finally surrendered on A Phillipine island in 1974.
Interesting.
Good movie. Watched it a couple of weeks ago.
There's a similar one from the same year, starring Michael Caine and Glenda Jackson (her last movie before she passed away), entitled "The Great Escaper". Very well done and worth seeing.
