Point to note. DVD got region code.
Budget willing, I would recommend BBC's world at war rather than something on the sg occupation.
http://www.amazon.com/World-War-30th-Anniv...76854789&sr=8-2There is a video store at Midpoint Orchard (next to the demolished Emerald opp somerset MRT should be B1 or 1st floor) which has a good selection of war documentaries (but slightly pricey). Not sure whether they're still there since I was there a few months back. You might want to take a look.
