Ten movies you must own on BluRay?

[sanbot]

1. Dark Knight
2. TF1/ROTF
3. Ironman
4. Anything from Pixar (Up looks particularly stunning, I also own Wall.E & Ratatouille on blu)
5. Fight Club
6. Tropic Thunder
7. Spider-man 3 (it looks great, that's about it :P)
8. Star Trek (new one)
9. Hellboy 2
10. Monsters vs Aliens
.

I'm curious as to why you included Fight Club and Tropic Thunder? Great movies but does it matter how good of quality it is to watch it?
