+ Eric Hodgins' bestselling Mr. Blandings Builds His Dream House was a quietly hilarious account of a man's troubles with a new house. Though Blandings was short on sex appeal, it sold more than 300,000 copies and was bought by the movies. Then Hollywood, which thinks sex is so important that it created a Production Code to keep sex out, added a triangle to the plot.
