"Hatchet for the Honeymoon" is a 1970 Italian-Spanish horror film directed by Mario Bava. The movie revolves around a fashion designer named John Harrington, portrayed by Stephen Forsyth, who is tormented by childhood traumas and a compulsion to murder brides on their wedding nights. He runs a bridal fashion house with his wife Mildred, played by Laura Betti. John believes that by killing these women, he can uncover the root of his psychological issues and put an end to his compulsions.

As the body count rises, Inspector Russell, played by Jesús Puente, begins to investigate the murders. John tries to maintain a façade of normalcy while conducting his killing spree, but his obsession becomes increasingly difficult to hide. The film delves into his distorted mind as he narrates his inner thoughts and struggles, giving viewers insight into his twisted motivations.

As the investigation continues, Mildred becomes suspicious of John's behavior and starts to suspect his involvement in the murders. John's grip on reality becomes more tenuous, and the line between his delusions and the real world blurs. The movie combines elements of psychological horror and slasher genres, with Bava's signature stylish and artistic direction.

The cast also includes Dagmar Lassander as Helen, an attractive model, and Antonia Mas as John's mother. The film is known for its visually striking scenes and creative death sequences, typical of Bava's style.
