As a concept it’s genius. Who needs Snakes On A Plane when you can have sharks in a supermarket? Directed by Kimble Rendall, the Wachowski’s favourite second unit director, after Razorback director, and Bait 3D co-scribe , Russell Mulcahy bailed on the project to shoot Teen Wolf for US television, Bait 3D is unapologetically trashy, a flick to be watched with brain turned off and belly full of beer and pizza.

The seemingly daft as a brush plot (although based on actual fact) is a zinger. Former lifesaver Josh (Xavier Samuel) is not happy with his lot. Year’s before, his best friend, and brother of his estranged girlfriend Tina (Sharni Vinson), was killed by a shark, and he blames himself. He is now wasting his life away in a dead-end supermarket job. On one particularly bad day at work, Tina appears with her new man as two criminals (Julian McMahon and Dan Wyllie) hold up the store, killing a checkout girl. Then the shop is hit by a tsunami, flooding the aisles, and underground car park, and forcing the shoppers to find safety atop the shelves. And then sharks begin to hunt for bargains.

The young good-looking cast do exactly what is required of them, be eaten by the world’s most ferocious carnivore. Twilight’s Xavier Samuel has seen the blood flow before in The Loved Ones and Road Train, Step Up 3D’s Sharni Vinson looks good teetering atop a supermarket shelf while Chronicle’s Alex Russell and a pair of Tomorrow When The War Began alumni, Phoebe Tonkin and Lincoln Lewis, make up the shark bait.

Technically Bait 3D is a marvel. The shark is a combo of animatronic beast and CGI number crunching, the 3D eye-pokingly fun, the gore devilishly gory, especially when the cast are dangling morsels trying not to dip their feet in the water and the action fast paced. Quick enough, in fact, to make you forget about the dodgy script and occasionally wobbly performances - plastic McMahon and outrageously ocker Wyllie chewing up the scenery - that rear their ugly heads.
