I too bought this without realizing it was Zone 2. In addition the retailer sent me and billed me for two copies even though I only wanted one. Like other buyers, the cost of returning the DVDs is almost as much as I paid.
I went one step further: I have a second, lighter laptop (14.5" screen) that I use for email when travelling, including very much in England.
I thought, OK, I can buy software that will let me reset the laptop four times to different Regions, then it is stuck in whatever the fifth choice is.
So I bought the software. I set the laptop to Region 2, as it states on the disk. My software states that the DVDs (both) are Region 4. I have no idea where Region 4 is and doubt I will ever need Region 4, so even a second laptop set to Region 2 (western Europe) will not help. The software is used, so I am stuck with that as well.
Disclaimer: Amazon.ca, since I am persistent and annoying, very kindly gave me a credit for one DVD. I certainly will use the credit since I buy lots of stuff here. (I bought the software from the developer, so that is another matter and certainly not the fault of Amazon.ca.)
Nonetheless, there should be a warning about DVDs from non-North-American vendors.
Indeed, why does Amazon.ca in Canada or Amazon.com in the USA offer Region 2 DVDs at all since they are of no use?
Concerning the movie itself: I have seen it several times on the big screen in the past and it is a great movie and reasonably accurate as far as history is concerned. That is why I wanted a copy I could see when desired. The movie "Waterloo" gets five stars.
The object that is for sale gets zero stars.
