Good movies to exhibit the differences in SD and HD formats

[trey]

I'm a collective addict (its my personality, ican't help it), so I've double dipped pretty much every title to my knowledge that would be a double dip. Look at my sig, I have a problem - that's all THIS year!!

My question though is which SD DVD should I keep to effectively exhibit the difference between blu-ray and DVD playing through a PS3.

I can't read all the titles from here, but there are mission impossible 2 and three, sahara, disturbia,spiderman3, superbad, descent, the first three harry potters,oceans thirteen, the terminator, the prestige crash employee of the month, deja vu, fantstic 4 1 and 2, lord of war,troy, corpse bide, resevoir dogs, superman returns, a scanne rdarkly, aviator, the covenant

i plan to get rid of most of these, but would like to keep one or two title-to-title for ocmparison and propaganda sake
