Just watched the high-resolution trailer for Terry Gilliam’s The Brothers Grimm (normal, boring Quicktime trailer here). The 720p version isn’t entirely smooth on my 1.25 GHz G4 Powerbook, but still quite gorgeous; upgrading to Quicktime 7 Pro and switching to full-screen mode improved it a bit (and, of course, enabled the various save and edit options as well).
The woman in the trailer who looks a lot like Claudia Black apparently isn’t, by the way.
