Australian actors Sharni Vinson (pictured above) and Xavier Samuel have been cast in directors Russell Mulcahy and Kimble Rendall’s upcoming creature-feature Bait 3-D. Set in a serene beach community overcome by a deadly tsunami, the film centers on a group of survivors trapped in a supermarket with man-eating tiger sharks.

I’m totally sportin’ a woody over this premise. When hurricane Katrina hit New Orleans and the streets flooded, I remember hearing that the sharks from the Aquarium of the Americas had been broken free and were feeding on a buffet of floating dead bodies.

Turns out that wasn’t true, but since then I can’t see a news story about a tsunami or flood without thinking how awesome terrifying it would be if maneaters became part of the equation.

Mulcahy, whose director creds include Resident Evil: Extinction and Highlander, further explained his vision in a video interview released awhile back.

Vinson cut her teeth in the States with guest spots on such popular shows as “Cold Case,” “NCIS,” and “CSI: NY.” The 27-year-old sheila scored her major motion picture debut this year in Summit Entertainment’s horrifying Step Up 3-D.

Xavier Samuel landed his own breakthrough role this summer as vampire Riley Biers in the Twilight Saga: Eclipse. He will next play the abducted crush of a psychotic wallflower in writer/director Sean Byrne’s award-winning TIFF darling The Loved Ones.

Bait 3-D also stars “Nip/Tuck” bad boy Julian McMahon, Alice Parkinson (X-Men Origins: Wolverine), cute up-and-comer Phoebe Tonkin, Damien Garvey (The Daybreakers), Lincoln Lewis (Voodoo Lagoon), Martin Sacks, Alexander Russell, Qi Yuwu, and Adrian Pang.
