When Jeff Golblum opens up his powerbook on the president's plane just before they take off, the camera pans around the computer, and you can see the clock tick down, and when it reaches one second remaining, they show a close-up of the powerbook, and the timer has gone back up to 2 seconds! The extra second didn't seem to help much, though.
It's much, much worse than that, Phil. If you can, put the whole scene into slow-motion right before Jeff G. turns his Powerbook around. That timer just goes through all sorts of crazy seconds. At one point it goes from 28:03 (i think) to 28:57! Their technical director must be from Palm Beach, Florida! (and their continuity people as well!)
I noticed that to. I know it's a bit nit picky, but it bugs me every single time I watch it. And what's worse is that it's really obvious, all of the extra seconds.
