A few details on what the Tasmanian wilderness is REALLY like.
I've spent a fair bit of time in western Tasmania, including places that are over a weeks hike from the nearest road. So I think I'm qualified to offer a few pointers to the producers in the (unlikely) event they decide to make a sequel.
* Everyone calls the animals "Devils" in Tasmania, NOT "Tas's". After all, if you're in Tasmania I guess everything there is "tas".
* Tasmanian Devils are solitary mammals, but the giant devils in this film hang around in packs and look more like reptiles or salamanders or something, not the bad tempered furry critters that I know.
* Tasmanian mountains are very rocky but with lots of jagged dolerite cliffs and spires, with a few mountains made of schist and other hard rocks, NOT the fairly smooth looking cliffs shown in the few location shots in the film. Almost every mountain with a huge cliff is high above the tree line and does NOT have a forest growing at the top.
* The mountain they jump off called Devils Peak (or similar) in the film is almost certainly based on a Tasmanian mountain called "Frenchmans Cap". 12,000 years ago it was sliced in half by a glacier leaving a 1,500 foot high cliff.
* Even at the height of summer, at night it is almost never warm enough in western Tassie to be comfortable in just a shirt. Anyone out there dressed in so little would look very cold.
* There are almost NO handguns in Australia. The only people allowed to have them are sworn police officers and Olympic shooters. No park rangers would ever have them. It's rare for park rangers to even have easy access to a rifle.
* The vegetation is a combination of cool temperate forests, with a lot of heathland. The treeless areas can be split between rocky alpine areas above the treeline and peat-boggy lowland "button-grass" areas mostly composed of muddy glacial silt. While many of the trees in the forested areas are varieties of pine, they look nothing like those Canadian conifers shown in the film. There are also plenty of tree ferns, southern beech (nothofagus genus), the occasional eucalypt and wattle and a giant sub-alpine heath called Pandanus that looks like a palm tree growing in snow country.
* The idea of offering a bribe to a ranger is preposterous. Doing so would automatically raise the charge from relatively minor trespassing that would attract a fine, to major crime status. In any case American currency is unknown, so it's unlikely a ranger would know what the bloke offering the bribe had in his hand.
* Surprisingly they got the Tasmanian Parks and Wildlife logo shown on their shirts and the door of the Four-Wheel-Drive just right, although the real one has different wording.
* Yes, the fake accents are utterly unrealistic. They really are shocking!
