"...about a poor little rich girl (Durbin) kept in an elite Swiss girls' school by a mother (Gail Patrick) who is a big Hollywood star and who, despite genuine love and compassion for her child, has kept her hidden so as not to tarnish her 'young' star image. In order to be on equal status with her school-mates, Deanna invents a rich explorer father - and finally challenged to produce him, kidnaps Herbert Marshall and sweet-talks him into playing the role.... (When) Deanna sings 'I Love to Whistle!' (it) is one of the most enjoyable images of pleasure from the late '30s." --W.K. Everson, Films in Review
