Meryl, you make me want to see Sunshine Cleaning. Good cast.
delalluvia, please to forgive, I came on this thread to say what a piece of barely mitigated crap Duplicity was, with annoying plot holes (plotholes being particularly irksome in thriller/caper/how'd they do it movies). I will agree that Julia Roberts didn't look good, but I like what I imagine you mean by the "organic" look, and am often not as keen on glamorous. To me it looked she had more weird plastic surgery and then bad make up. Clive Owen, I concur, is pretty dang yummy, and so interesting to look at. And he did do a good job on the accent, though it didn't sound like any Tennessee accent I'm familiar with. He could do a whole movie with that accent and carry it off, I think.
The dialogue was incredibly lame-o. I didn't feel chemistry between them other than I kept getting the sense they were signalling, "I can't believe I'm delivering this horseshit." "I know, we've sold out, but remember, it's worth it." "I guess. Where do you want to go for lunch today?"
I did like Kathleen Chalfant.
I went to the IMDb forum for it, and read some pretty entertaining plot hole explosions.
