USA uses NTSC, which is 24 frames per second. Germany and UK use PAL which is 25 fps. Over the length of an average movie the PAL version will "lose" about 5 minutes, but all the frames are still there.
NTSC is 29.97 frames per second (aka 60i for 60 interlaced 'fields' per second), but on DVD and BLU RAY, NTSC DVD players (and PAL/SECAM) all can play 24 frames per second film (aka 24P, which runs at 23.976 frames per second)
For the record, I got the official word from Focus that they will not be putting out a Brick blu-ray in the states. Their reason was that "thrillers and noir" do not sell well on blu.
That is ridiculous. All distributors have the possibility of doing limited runs, even if that "limit" is 10,000. The rental houses alone could cover that and they'd still be in profit.
Distributors are morons so far removed from their own customers.
