The film stars Nathan Jones, John Jarratt, Christie-Lee Britten, and Melissa Tkautz, with special appearances by Chris Haywood and Steve Bisley.

As they recover from the shock, they notice a feral pig stampede before a massive man-eating boar as big as a rhinoceros slams into their truck, killing them.

Later, when Bernie takes his family out for a day of fun, he briefly leaves to search for Ken and Blue, only to have his truck attacked by the boar.

By this point, the two women have constructed multiple fires to try and keep it away, but the boar attacks as they try to fend it off with their torches, managing to savage Ella's leg.

Anton Bitel from SciFi Now criticized the film for its uninteresting characters, derivative plot, and repetitive revealing of the title monster.

Bitel concluded his review by writing," For while Boar plainly advertises the big beast to come, it also hints homophonously at an absence of sufficient entertainment to see us through its duration.

Jonathan Barkan from Dread Central awarded the film three and a half out of five stars, writing, "Hindered by strange pacing and restrained by the limitations of a giant practical pig, Boar still manages to be a thoroughly entertaining and wildly savage bloodbath through the beauty of the Australian bush.
