Dave Franco and Alison Brie are actually married in real life.

The screenplay is based on the first tale of the third day from The Decameron (1971).

Writer and director Jeff Baena only wrote a detailed outline for the film, which was loosely based on "The Decameron". The cast improvised their dialogue.

The joke in the title is that the word "Hours" is suppose to be pronounced as if there were a "W" at the beginning of the word.

Dave Franco, Kate Micucci and Molly Shannon have appeared in the TV Series Scrubs (2001).

Nick offerman and Aubrey Plaza worked together on Parks and Recreation.
