I woke up this morning to an email from Katherine suggesting that Isabelle Huppert and Amy Madigan might be a good fit for Celebrities That Look Alike. I AGREED! I pulled a picture of a particularly young Amy Madigan (even younger than Uncle Buck Amy Madigan!) in order to fully show her similarities to Isabelle Huppert (better known as Catherine Vauban to us all), which are grand.
I'm thinking Sisters, there were never such devoted sisters!
