Impulse

Impulse is a crime thriller film released in 1974, directed by William Grefe with William Shatner delivering a memorable performance as Matt Stone, a swindler with an ingrained psychopathic streak. The film also stars Ruth Roman and Jennifer Bishop, who bring their unique talents to this twisted tale of deceit and death.

The plot is a chilling exploration of a dark mind, set against the backdrop of a sunny Florida tourism city. The movie's scenic beauty contrasts with the chilling storyline, contributing seamlessly to the suspenseful atmosphere—it's a striking contrast that sets a unique ambiance to the movie.

William Shatner's impressive portrayal of Matt Stone, a conman with a deeply troubling past whose charm and persuasiveness allow him to seduce unsuspecting women out of their money, is the pulse of Impulse. Stone is not your standard villain, as Shatner skillfully injects an enigmatic impishness into his character. His jarring unpredictability and seemingly benign exterior mask a terrifying propensity for violence – a façade that keeps the audience on the edge of their seats. Shatner uses his charisma and charm to make Stone a character whom audiences love to hate—an alluring and dangerous figure whose compulsions drive the story forward.

Ruth Roman, an established actress known for her roles in classic Hollywood films, plays the role of Julia Marstow, a wealthy widow whose vulnerability and loneliness make her the perfect prey. Her nuanced performance heightens the audience's empathy for a character tragically oblivious to the violent tendencies of her dashing new suitor.

Completing this murky love triangle is Jennifer Bishop, who portrays Ann Moy, a dance hall girl and single mother who falls for Stone's misleading charm, painting a picture of individuals who tragically fall prey to the whims of a cunning psychopath.

Film director Grefe's adept handling of this complex psychodrama is noteworthy. He cuts right to the chase, using the sunny Florida location to highlight the film's core narrative - how menace lurks in the sunniest places, often disguised behind a charming facade. The narrative maintains a gripping tension throughout and overlays intriguing subplots that keep the film moving at a brisk pace.

Impulse serves to underscore Grefe's capacity to squeeze every ounce of suspense out of any given story. Coupled with Shatner's unpredictable performance, it's a polarizing thrill-ride that sends shivers down the spine.

Technically, the film features above-average cinematography, ensuring the lush landscapes of Florida are as much a character in the movie as the human cast. The juxtaposition of the sunny, scenic backdrop with the dark, twisted plot creates a jarring but effective production aesthetic.

The film's score also adds a haunting layer to the already tense narrative, accentuating the nail-biting suspense scenes and underscoring the more tender, dramatic moments with touching melodies. The soundtrack displays an exceptional blend of mood-enhancing compositions that heighten the film's dramatic tension.

Impulse is not just another thriller; it's a chilling exploration of the mind of a psychopath, a man who uses his charm and wit to manipulate and kill. It's a stark reminder of the monsters that hide behind the most charming faces, those we least expect. It's an experience that will leave you questioning trust, charm, and the seemingly innocent impulses of strangers.

The film seduces the audience into a world of sun-soaked streets and charming people but swiftly pulls the rug from under, exposing the sinister underbelly of mankind. The narrative's standout factor is its ability to consistently lull the audience into a false sense of security before blindsiding them with another shocking revelation, which keeps you gripped.

Impulse, while a product of its time, remains eerily relevant today. Its core message, carried by powerful performances and dramatic narration, is a timeless study in vulnerability, manipulation, treachery, and raw human emotion. It offers a shivering portrayal of blind trust's dangerous consequences, reinforced by masterly performance, direction, and a fitting score.

In conclusion, Impulse is a thrilling, suspense-filled dive into the dark depths of human nature. It's a film that writhes and twists, just like the central character’s psyche, keeping viewers on their toes till the very end. If you appreciate well-constructed thrillers with unpredictable anti-heroes and a narrative that dips and sways like a roller-coaster, Impulse should be on your cinematic radar.
