As a recent owner of a PS3 (which has a BluRay player), I wanted to buy a small selection of movies to make the most of it (and the full HD TV I have).
The reason I only want a small selection, is because I already have a heap of DVDs, and don't want to be doubling up unless it is absolutely worth it.

So, basically I am after recommended movies, that are at their full potential with High Definition (and Sound), or are best viewed at that standard.

Reasons are optional, but would help with my choices.
