I saw them in The Goodbye Girl, and was a little disappointed. Short was breaking character and Peters couldn't keep a straight face. But that was years ago, and Short has proven himself as an actor since then. So, I'd definitely go see them in this. I've had a sort of love/hate thing with Peters over the years, but I think she's well suited for this.
