Un Amour de Poche on AllMovie

Filmed in 1957 but not released in the U.S. until 1962, Girl in His Pocket was released to more liberal markets as Nude in His Pocket. Jean Marais plays Prof. Jerome, a researcher who is intrigued with the theory of suspended animation. With the help of his sexy assistant Monette (Agnes Laurent), the professor stumbles upon a formula that shrinks people and turns them into living statues. When the professor's wife suspects that her husband is carrying on a romance with Monette (she's right), the au naturel Monette hides herself by drinking the potion and secreting herself within the professor's pocket. There's a race to the rescue when the professor's wife places the "figurine" Monette on an ocean liner bound for parts unknown. Girl in His Pocket was based on "The Diminishing Draft", a short story by Waldemar Kaempfert, originally published way back in 1918.
