Hey, some interesting titles. 

I own Magnolia and 25th Hour on DVD, and Last Days on VCD. Starship Troopers still holds a place among my dozen original VHS copies I haven't sold. Not a guilty pleasure at all, I find it a great satire on American society. And I haven't watched Showgirls, yet. 

I hHve also been on a shopping-spree the last couple of weeks and have bought some DVDs (most of them cost me between 3 and 6 Euros).
Now here are some guilty pleasures!
