Assuming that you are referring to the 2008 movie, Disgrace is yet to be released in a few countries, according to IMDB. The film does not appear to have been released on DVD, as of yet, and I think you may have to wait a while. It is possible that you might be able to find it at somewhere like Netflix, but a quick look via Google didn't produce any full versions of the movie online, just trailers and interviews.
Perhaps someone else can come up with a link, but it appears to be a case of waiting I'm afraid. Good luck finding it.
toronto.com/drama/listing/642640#showtimes If that direct link doesn't work try toronto.com/movies and type in the name but from what I can see (my work computer however is crap) @witchmojo is correct, if hasn't come out yet for you north of the border.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
