IMDb has pages for the second and third movies, but no hard information.
I'll certainly at some point watch the US version, but not for a while yet, and I have to admit to being predisposed to not liking it. Or not liking it as much as the Swedish.
I like some Fincher, but I know how my tastes run when it comes to good foreign films and US remakes, and I expect to find this one a multi-million-dollar overproduced Hollywood extravaganza with lots of "now" stuff (to shamelessly plagiarize BK's descriptions of things). Of course, knowing nothing about it, I could be totally wrong about this one.
