General:
The DVD feature, "Better than Botox," shows how the post-production team made Gary Sinise look 15 yrs younger for the flashbacks.
Mac's parents' names are McCanna and Millie Taylor. McCanna is the name of Gary's wife Moira's oldest brother (a decorated Vietnam War hero), and Millie is Gary's mother's nickname.
