Gave my new 73" DLP it's maiden power up last night. HDMI Bluray w/ District 9..... !@#!!!!!!!!!!! Best money I spent all year.
Planning on watching The Thing tonight with some friends over.
Next step is to upgrade the receiver w/ an HDMI compat one. Maybe this weekend. 
Also, not exactly old flicks, but for films that look really good in 1080p, consider Wall-E, Serenity, and even Riddick. They stand out in my book as some of the best looking hi-def flicks, though not exactly the best flicks, heh.
