The Final Cut 2004

In the future, microchips implanted in your brain record everything you see and here. Then when you die, a 'cutter' assembles the footage into a memorial video for your funeral, editing out all of the unpleasantness. The most sought-after cutter is Alan Hakman (Robin Williams), a detached man who believes his work can absolve the dead of their sins. While editing the memories of another cutter, he uncovers a disturbing piece of his own past which leads him to question the way he's lived his life.
