DVDs - What should I keep?

When you realise that you have to move house, if you are me, you take a step back and gaze in ore to see how much stuff you have. Even over 12 months, my collection of books has doubled, I have a huge pile of magazines that I want to keeps, a mass of clothes and big stack* of DVDs.

I had quite a big decision to make as I realised that I would have to pack all of my stuff into the back of a Renault Espace. What should I keep, what should I sell and what should I give to a friend.

For me, the way I worked out what was going to stay and what was going to go, I took the following approaches:
1 - Is this a film that I want to pass on to friends, family and friends children in the future as a 'Must Watch'?
2 - Have I seen it? If not, is it one that I definitely want to see?

As I boxed away my DVD's to get rid of, I had a thought. Even though some of these films are classics or ones that I have never seen. I can always get them again. I could add them to my LoveFilm list or even take a gander through iTunes to see what I can rent.

Anyway, these are the films I decided to keep...What do you think?

My MUST Watches:
Breakfast at Tiffany's - Classic film and one that everyone should see!
