Mirror Mirror

Mirror Mirror is a 1995 Australian/NZ co-production about the goings-on in both 1919 and 1995, after they find out that they can access each other's timelines through an antique mirror.

The 1995 side involves Australian Jo Tiegan (Petra Jared), whose mother has just been appointed principal of a New Zealand school and has dragged the entire family with her. On a trip to the local shop, Jo finds herself inexplicably drawn to an antiques store run by a strange old man who knows her name, and insists that not only does she take an old mirror he owns, but also that he personally places it.

Jo soon discovers why this was necessary: the mirror functions as a portal to the year 1919, when the place was owned by the Iredale family, whose neighbour Sir Ivor Creevey-Thorne is housing a young Russian named Nicholas.

Meanwhile, in 1995, a dig at the school leads to the discovery of a canister of toxic chemicals in a well, which is then accidentally sprayed on two students. With both students' lives hanging in the balance, Jo and her newfound friend Louisa race against time to prevent this from ever having happened.

Not to be confused with Gregory Maguire's Darker and Edgier literary remake of Snow White of the same title, or with the 2012 film of the same name.

This series contains examples of:

 * Adults Are Useless: The Old Man is the only one who has any clear idea of what the hell is going on . Louisa's family never find out, and their tutor turns out to be in the pay of Sir Ivor, who only wishes to sell Nicholas back to Russia. Jo's family eventually do find out, but it turns out that only Louisa, Jo and Jo's brother Royce can actually use the mirror properly.
 * Fridge Logic:
 * Portal to The Past: The mirror.
 * Portal Slam: The mirror must be placed in exactly the same place at both ends in order to function properly (at one point, it has to be taken on a train. Also:
 * Temporal Paradox: Tama and Jo insist on remaining in 1919 just to see.
 * Timey Wimey Ball:
 * Xanatos Roulette: The old man uses an Omniscient Morality License to carry out one of these. It turns out that but that doesn't matter because.
