Maria Mannelli is another generica who can be found in many movies in the 1950's-1960's, but her most famous role is in I mostri (1963), as the unlucky Mrs. Cecconi, an older woman who is kidnapped by the crew of an eccentric director, in order to make her the star of a scene in which she's forced to jump in a pool... for 13 times!
