Knife Edge is a 2009 psychological thriller directed by Anthony Hickox and stars Hugh Bonneville, Natalie Press, and Matthieu Boujenah. The film revolves around the lives of a wealthy British family, whose luxurious lifestyle is threatened by a series of unsettling events. The story follows the character of Emma, played by Natalie Press, the wife of a successful investment banker called Alfie, played by Hugh Bonneville. Alfie is a workaholic, who neglects Emma and their two children - 10-year-old Tom and 5-year-old Ozzy - in his pursuit of success. Emma, who struggles with the pressure of being a full-time mother and wife to a man who is rarely around, finds solace in an affair with her French art dealer friend named Gabriel, played by Matthieu Boujenah.

Alongside these struggles, the family is tormented by strange occurrences in their mansion in London. The house is home to several expensive artwork pieces that Alfie has collected over the years, and the family thinks that the thefts in their home are orchestrated by someone who has taken an interest in their collection. Things take a deadly turn when the family hires a new nanny and things start to spiral out of control.

As Alfie becomes more and more obsessed with his work, Emma starts to lose control of her life. The family's ex-nanny suddenly appears in their house, bringing with her the dark secrets of the past. The new nanny they hire seems to have a mysterious past, creating a rift between Emma and Alfie, as they argue about whether to trust her or not. Alongside this, the family's wealth and privilege create rifts between the family and their staff, making it hard for them to trust anyone around them.

As the tension builds, Emma tries to protect her family, but the constant chaos in her life starts to become too much for her to handle. The constant state of fear and confusion takes a toll on her, leading to devastating consequences. The family's luxurious life falls apart as secrets are exposed and relationships are tested.

The acting in Knife Edge is superb, with Bonneville's portrayal of Alfie being particularly impressive. He brings nuance and depth to his character, making Alfie simultaneously sympathetic and unlikable. Natalie Press as Emma is also strong in her role, giving a heart-wrenching performance as a woman grappling with the stress of a crumbling marriage and the safety of her children.

The film's use of sound and music heightens the tension, as does the cinematography, which expertly captures the grandeur of the family's mansion and the claustrophobic intensity of their lives. The film's pacing is also effective, building the suspense gradually until it reaches a thrilling, unexpected climax.

In conclusion, Knife Edge is a gripping psychological thriller that offers a glimpse into the lives of a wealthy family and the struggles that come with their privilege. The acting, direction, and cinematography work together to create a tense and haunting atmosphere that will linger with you long after the credits roll.

Knife Edge is a 2008 horror movie with a runtime of 1 hour and 30 minutes. It has received mostly poor reviews from critics and viewers, who have given it an IMDb score of 4.5.
