Witness

To prepare for her role, Kelly McGillis lived with an Amish widow and her seven children for a while before filming began.

The Amish neither speak nor understand modern-day High German. They speak Pennsylvania Dutch (Palatine German or Pfaelzisch), a Franconian dialect.

The closing shot of John Book driving away in his car passing Daniel provides an initial backdrop for the end credits.

In the original theatrical stereo mix, just after John Book is shot, we see a close-up of his gun and a voice-over from an earlier conversation Book had with the captain. We hear the words: "Who else knows about this? "Just you and me." In the DVD version, which contains a remixed 5.1 track, we see the close-up of the gun and then it segues to Book's sister waking up Rachel and her son Samuel, but the voice-over is missing. In addition to that, there are also new sound effects like ambient noise and especially gunshots added throughout. However Arrow's 2023 4K release restores the theatrical mix which contains the original sound effects and the missing parking garage dialogue.
