You already know what to expect from Piranha 3D before you even settle down in your seat with a bucket of popcorn and drink.

Kelly Brook, who plays glamour model Danni, has described the 3D remake of the 1978 horror as ‘a big, fun B-movie with lots of boobs, blood, gore and drama’, and there are plenty of these ingredients in this cheesy romp to keep horror fans satisfied.

French filmmaker Alexandre Aja – of The Hills Have Eyes fame – has turned his hand from mutants to the flesh-eating piranhas, which unsurprisingly show little mercy as they chomp and chew their way through fresh-faced teenagers and fun-seekers celebrating their annual spring break festivities.

Sheriff Julie Forester (Elisabeth Shue) is a working mum who has to leave her teenage son Jake (Steven McQueen) to babysit her younger children as she heads off to patrol the spring break parties at Lake Victoria – but Jake would rather spend time with porn king Derrick (Jerry O’Connell) and his two glamorous busty sidekicks Danni (Brook) and Crystal (real-life erotic actress Riley Steele).

Jake helps his new friend find a quiet spot at the lake to shoot scenes for his new film, which includes a raunchy kiss between the two actresses.

The tranquil spot just so happens to be the same area where a recent underwater tremor opened a deep chasm, unleashing swarms of prehistoric razor-toothed fish that had been dormant for thousands of years and now have a taste for human flesh.

‘This particular piranha vanished two million years ago,’ explains Goodman (Christopher Lloyd).

They may have been extinct at one point, but the killer fishes predictably make up for lost time as they terrorise the former beauty spot and the body count racks up in inventive and oddly amusing ways.

One bikini-clad girl gets a nice nip on her bottom as she wallows on a rubber tube in the sea, while another meets her nasty end as she laughably tries to fight them off with a frying pan.

Forester and a small team of survivors try to outwit the predators, and attempts to make the lake off-limits to the tourists.

Her colleague Deputy Fallon (Ving Rhames) helpfully said: ‘It’s us and 20,000 kids.

You do the maths,’ before being shocked by the gruesome discoveries: ‘It’s like the bodies have been in the water for weeks.’ The 3D adds a touch of fun to the horror – with fish and ample chests popping out – and although the effects look fake at times, guys will surely appreciate the amount of bouncy assets and bikini-clad women around.
