The Wedding Date (2005) Review
Kat (Debra Messing) is fairly miserable. She's been invited to a wedding and her ex will be there. Worse yet, she doesn't have a date, so she does what any woman would do. She hires an escort. Yes, an escort.
Nick (Dermot Mulroney) will be her date. She pays him six thousand dollars and gives him a first-class plane ticket to London to show up and be wonderful, which she figures will make her ex insanely jealous, winning him back (or at least making him feel miserable, which is at least as good).
