First comes love, then comes marriage, then all your friends are too busy pushing baby carriages to spend time with you. This cultural phenomenon is what inspired writer-director-producer-star Jennifer Westfeldt‘s upcoming Friends With Kids, an indie movie the Kissing Jessica Stein star is hoping will premiere at this fall’s Toronto Film Festival. She and Mad Men‘s Jon Hamm, who costars, have been a couple since 1997, and since they don’t have children, they get a lot of pressure from their own friends with kids. Explains Westfeldt, ”We’ve noticed everyone who has a child wants you to immediately have a child.”

Hamm plays a father whose marriage to Kristen Wiig is crumbling, while Westfeldt’s character decides to have a child with platonic pal Adam Scott. The all-star cast also includes Edward Burns, Megan Fox, Maya Rudolph, and Chris O’Dowd. ”Yes, we have half the cast of Bridesmaids in this ensemble,” admits Westfeldt. She and Hamm, who produced the movie through their own Points West Pictures, often avoided agents and managers while recruiting friends and previous costars. ”So much of this industry is…” begins Westfeldt, before Hamm finishes: ”…getting around representatives.” So while they may not be a cutesy couple with a stroller, they are a cutesy couple who can finish each other’s sentences.
