How to Be a Perfect Person in Just Three Days is a 1984 American television family comedy film directed by Joan Micklin Silver and written by Bruce Harmon, based on the 1982 children's book Be a Perfect Person in Just Three Days! by Stephen Manes. It stars Wallace Shawn, Ilan Mitchell-Smith, and Hermione Gingold.
The film first aired on PBS on October 4, 1984,[1] as part of the series WonderWorks, and was regularly shown on The Disney Channel in the mid-1980s.
The film depicts a twelve-year-old boy named Milo, a hopeless klutz who happens upon a mysterious advertisement in the paper for becoming a perfect person. On offer is a three-day course devised by a peculiar man, Dr. Silverfish. Milo enrolls and manages to complete the strange tasks. Only after completing the course does Milo realize that perfection is a lot more boring than he thought it was (mainly because it involves never doing anything so as not to make mistakes).
