Jon Hamm has been in a relationship with the marvelous Jennifer Westfeldt for many years, and has been in all of her movies. Most recently, he had a large supporting role in Friends With Kids, a romantic comedy about two platonic best friends (Westfeldt and Adam Scott) who decide to have a kid together. Here’s my review from 2012. Note the hideous Photoshop poster image.
Scott and Westfeldt are part of a group of six friends who’ve known each other a long time, including Hamm and Kristen Wiig as a married couple.
In the scene below, four couples (our core six friends plus Westfeldt’s boyfriend and Scott’s girlfriend) have a New Year’s Eve dinner, and Hamm gets a crucial scene. It gets juicy around four and half minutes in.
