Dear Brigitte (1965) RE-UP

Erasmus (Bill Mumy) ist ein achtjähriger Wunderknabe, dessen Zahlengedächtnis phänomenal ist und dem das Musizieren als Cellist der familiären Hauskapelle absolut nicht behagt. Sein Vater Leaf (James Stewart) hingegen hat dem abstrakten Denken und der Mathematik den Kampf angesagt. Für ihn, den liebenswerten Literaturprofessor, der Zahlen verabscheut, droht der Himmel einzustürzen, als sich die Welt um seinen Sprössling reißt, den 'menschlichen Computer'. Doch der kleine Erasmus hat nur eins im Sinn: Ein Treffen mit der französischen Filmgöttin Brigitte Bardot, der er mit rührender Emsigkeit Liebesbriefe am laufenden Band schreibt.
–––––––––––––––––––––––
Robert Leaf, poet and professor teaching at a California college, lives on an old ferryboat with his wife and family and is devoted to the arts but detests science. Unnerved when he discovers that his 8-year-old son, Erasmus, is both tone-deaf and colorblind, he is further horrified to learn that Erasmus is a mathematical genius, and Leaf does his best to keep this a secret. Leaf's daughter, Pandora, begins having her brother do her homework, and she and her boyfriend Kenneth soon have Erasmus handicapping horses for them. They begin to pile up money while Erasmus saves the fees he charges them for a trip to Paris to meet Brigitte Bardot, to whom he has written many letters. A con man calling himself Dr. Peregrine Upjohn makes a proposition to Leaf that they finance a Leaf Foundation to set up scholarships for students of the arts and humanities by having Erasmus handicap horses, and Leaf agrees. The foundation's assets soar until Erasmus refuses to perform his function unless he can accept an invitation he has received to visit Brigitte Bardot in Paris. Leaf takes him to Paris, where he actually meets Bardot, and while they are gone Upjohn plans to abscond with the money. An Internal Revenue agent claims the money from Upjohn, but Leaf and Erasmus arrive in time to inform the agent that the foundation is nonprofit and therefore tax exempt. Leaf takes the money, and life on the ferryboat returns to its usual pattern.
