Black Water (2007) is an Australian survival horror film directed by Andrew Traucki and co-written by Traucki and David Nerlich. A chilling, realistic thriller, it draws inspiration from true events and presents a terrifying story about a group of friends who become stranded in the remote mangroves of northern Australia, where they encounter a mᴀssive, aggressive saltwater crocodile.

The film opens with a seemingly innocent fishing trip, where friends Grace (Diana Glenn), her boyfriend Adam (Andy Rodoreda), and her sister Lee (Maeve Dermody) head into the wilderness for a relaxing getaway. However, things quickly take a dark turn when their boat capsizes and they are left stranded in the mangrove swamp. The trio must then fight for survival, trying to escape the ever-present threat of the crocodile that lurks beneath the water.

One of the most effective elements of Black Water is its minimalistic approach to horror. Rather than relying on gore or jump scares, the film creates a tense atmosphere by focusing on the vulnerability of the characters and the constant, unseen presence of the predator. The swamp setting adds to the sense of isolation and claustrophobia, amplifying the tension as the characters struggle to stay out of the water.

The performances are grounded and believable, with Diana Glenn delivering a particularly strong portrayal of Grace, a character who must tap into her resourcefulness and bravery to survive. The relationship between the characters feels natural, which heightens the emotional stakes as their situation becomes increasingly dire.

While Black Water excels in building suspense, it suffers from moments of uneven pacing. The film occasionally lags, and some viewers may find the slow burn frustrating. However, its unflinching realism and visceral tension make it a compelling experience for fans of survival horror. Black Water is a gripping, survival-based thriller that delivers tension without relying on supernatural elements, making it a standout in the genre.
