Well, like you, I had many thoughts after watching Contempt the last time, but they have all slowly vanished or been absorbed. The above is probably the most you could get out of me, beside maybe a few more questions. I'd like to see it again, but the film is a bit "heavy", and I don't think i'm up to it at the moment. 
Voyage in Italy is a good point, I think you should check it out. But it's different, in that less is spoken about the relationship, and it's less complicated than in Contempt. The couple is kind of standard middle-aged upper middle class. I didn't like the film too much, but there are some beautiful and stunning scenes involving some greek mythology. 

BTW, I think Alphaville was intended as Godard's love-letter to Karina (also photographed by Coutard), can't imagine Contempt in that function...

Sadly I don't have MSN, but if you stick around this Forum, I'll surely recall your adress (or this thread), when I'll get it.
