Casting Suggestions For How to Be Single

News that Drew Barrymore has signed on to direct the movie adaptation of How to Be Single didn't just excite me because it sounds like it could be a cute romantic comedy; I'm more invested because I'm currently reading the book by Liz Tuccillo. The story is about five single friends in their late 30s living in New York City and each dealing with the challenges of her own love life. Though casting hasn't begun, I have some actors in mind to play the female five-some and their love interests, assuming that Barrymore will pluck her cast from her personal group of friends and costars.
