Re: Polanski, I've seen KNIFE IN THE WATER, CUL DE SAC, THE TENANT, thought they were all excellent. They have a great atmosphere of unease, THE TENANT especially.
Re: ARKADIN remake, this current vogue of Welles-remaking reminds me of the period a couple of years back when the same thing was happening with Hitchcock. That vogue didn't turn out very well, I doubt this one will. On the other hand, if the producer Mark Johnson is the same one who produced Mike Newell's film of DONNIE BRASCO, then the new ARKADIN may be half-decent, though of course the important thing is: who's going to direct?
Even if it turns out for the worst, the remake will attract attention to the original film, which must be a good thing.
Van Stratten casting: How about Tim Roth?
