The Peanut Butter Solution (1985) trailer
The Peanut Butter Solution (French title: Opération beurre de pinottes) is a 1985 family horror fantasy film. The movie was directed by Michael Rubbo and is the 2nd in the Tales for All (Contes Pour Tous) series of children's movies created by Les Productions la Fête.
Michael Baskin is an average 11-year-old boy. His father, Billy Baskin, is a struggling artist and temporary sole caregiver of the children while his wife attends to the needs of her recently deceased father in Australia. Upon hearing the news that an abandoned mansion has recently burned down, Michael and his friend Connie decide to explore the remains. Outside the mansion, Connie dares Michael to take a look inside, leading to a frightening encounter with the ghosts of its homeless inhabitants who had died in the fire. Michael does not know this yet, but his fearsome run in with the ghosts has given him a mysterious illness simply known as "The Fright". Michael wakes up the next morning to find out that "The Fright" has made him lose all of his hair. After a failed attempt with a wig (his wig was pulled off by an older boy during a fight in a soccer game), the ghosts visit Michael in his sleep and give him the recipe of a magical formula for hair growth, the main ingredient of which is peanut butter. Michael's first attempt to make the formula is thwarted when his father and sister think he is making something to ingest (rather than use topically) and dispose of it.
The ghosts return the following night, giving themselves a second chance to pay him back for giving his money to some homeless people, and also give Michael special instruction not to add too much peanut butter, as it will end in dreadful results. Michael successfully makes the formula this time, but ignores their instructions not to overdo the peanut butter, and wakes up the next morning to find that his new hair has already begun to grow. After only a few minutes, Michael has grown a full head of hair. Suspicious of his fast growing follicles, Connie confronts Michael about his unusual ability. When Michael reveals to him his concoction, Connie decides to apply some to his pubic area, in an attempt to create the illusion that he's going through puberty. Connie soon discovers that the joke is on him. Pretty soon, Michael and Connie's hair grows to such lengths that it has become a nuisance for the school and their classmates, resulting in their suspensions. While Michael frantically searches for a solution, Connie discovers that the hair will stop growing by yelling at it.
The art teacher at Michael's school, simply called the Signor, frightens children and forbids them from using their imagination. After getting fired from the school, the Signor finds out about Michael's condition and kidnaps him (and many other neighborhood children) to make magic paint brushes from Michael's ever-growing hair, in which he subdues Michael with a knockout drug. The kidnapped children are put to work under tough conditions. "We have to make 500 brushes a day, or we don't eat!" The paintbrushes are so powerful that they paint whatever their user imagines without need for detail or neatness. Connie, and Michael's sister, Suzie, discover the Signor's magical paintbrush factory and try to rescue Michael. Connie tries to use force, but he is overpowered by Signor and his dog James. Instead, Connie tricks the Signor into painting a picture of the abandoned mansion. Connie then dares him to investigate inside, leading "The Fright" to be passed on from Michael to the Signor. The Signor, now bald, escapes from the haunted house and chases the children, locking them up. Just as Connie is about to escape with Michael, Susan and their dad find the factory and the Signor is arrested by the local police. The film ends with the family reunited as the mother has returned home, and Michael's hair has stopped growing out of control.
