The Happy Couple: Amy (Amy Adams) and Edward Fletcher-Wooten (Jack Davenport)

The Hanger On: Kat (Debra Messing)

What’s the situation? Amy’s getting married in London, but her sister Kat is panicking because Kat’s ex Jeffrey (Jeremy Sheffield) is best man. Kat is morbidly convinced that attending the wedding without a date will convince Jeffrey that she’s a loser at life and scupper any chance she has of getting him back (which she wants, or whatever). So she hires a male escort to turn up with her, in the shape of Dermot Mulroney – him again – as Nick. He does such a good job of convincing everyone they’re in love that Jeffrey, the cad, takes an interest again, but maybe Kat really prefers Nick after all (obviously) and takes the man-whore over the bounder. Meanwhile, Jeffrey’s revealed as an even worse human than we already thought, Nick turns out to be a paragon and Ed and Amy have a brief wobble before ending up happy ever after.

Worst moment: The whole premise of the film, really. That, or the revelations in the boat house.

Moral of the story? You’re exes for a reason: get over it. Also, someone who is demonstrably a success in every other possible way – career, apartment, fabulous hair – should be able to turn up to one simple wedding alone.
