Anti-Nazi resistance fighter and Jean Cocteau paramour Jean Marais (La Belle et la Bête) starred in this 1957 trifle originally released as Amour de poche. Agnés Laurent (The Twilight Girls) is Monette, lab assistant to Marais' Professor Jerome, who resides in his jacket pocket after drinking a serum that shrinks her - but not her clothing - to the size of a candy bar. Geneviève Page (Belle de Jour) is the prof's scandalized fiancée. Filmmaker Pierre Kast (The Season for Love), also a former freedom fighter, wrote for Cahiers du cinéma in addition to directing dozens of films.
