Preston Sturges wrote this script and it is his hand which lies on this comic wish-fulfilment fantasy rather than director William Wyler's, or author of the play, Ferenc Molnar. Maureen Sullavan is Lu Ginglebusher, rescured from an 'orphan asylum' by to work as an usherette in a picture palace, but rapidly finds herself taken out of that world and placed under the wing of hotel waiter, Detlaff (Reginald Owen) who can do nothing to save her from the admiring attention of bored, ageing millionaire, Konrad, beef king of Latin America, played with chattery gusto like a youthful Wiener King (Palm Beach Story) by Frank Morgan.
'Good fairy' Maureen Sullavan tries to keep up her vow of doing one good deed a day and she sees an opportunity when the millionaire offers to make her rich, a gift she realises he would make to anyone she cares to nominate. Here is her opportunity to bring 'Christmas in July', but who to? Not the orphanage, anyway. That never seems to occur to her, and at a loss she turns to the phone-book and selects the 'poor-looking' name of lawyer, Dr Max Sporum (Herbert Marshall). He is soon the recipient of 120,000 a yaer (kroner). But has she done the right thing?
