I own Demonlover on DVD, but when I wanted to watch it last year, I noticed that it has only a german language track. 
That's why I got it so cheap, alongside Chereau's magnificent Son frere. Will have to seel both, and by better editions in the future.

I tried watching Mann's Collateral yesterday, but I was too stoned. I own the 2-disc special edition, and will watch it another time, but somehow I expected the cinematography to be better (after watching Miami Vice, that is).
The problem with the characters in Miami Vice for me was that Mann didn't give them enough depth (certainly not for an engaging love Story). So I wish he would have focused more on the operations, as this seemed to be his primary interest. (I#ve also read an interesting interview with him on that topic).
