 Chris says the movie is based on an old French film called Chloe in the Afternoon, which he picked up while shopping one day. After watching it, Chris called his friend Louie and asked him to watch it, too. "Me and Louie, we're both married. We both have two kids. We both live outside of Manhattan," Chris says.

Chris and Louie decided to write their own version of the movie. "We just thought, you know what? It's time for me to do a grown-up movie," Chris says. "It's time for me to play a grown man with grown problems. ... And I wanted to do a serious comedy."
