It's 10 minutes long. This is found on the season 1 DVD of Without A Trace. It spoils a lot of the season, and so will this review, so that I can go into more detail.
They talk about Jerry Bruckheimer telling them that even if you were channel hopping with the sound down, the show would be visually arresting. Spending a lot of time dressing extras. Giving each lead a distinct look that fits their personality. The disappearing toddler. The set design of the FBI office, and its lighting setup, and how they're able to do Steadicam shots without worrying about accidentally showing where the illusion ends. Research.
I recommend this to any fan of the property. 8/10
