The Happy Couple: Whoever they can find.

The Hanger On: John (Owen Wilson) and Jeremy (Vince Vaughn)

What’s the situation? John and Jeremy are lawyers who do everything together, including crashing every wedding they can and pulling like demons while they’re about it. But when John leads them in pursuit of Claire (Rachel McAdams) on a weekend back at the family home, and Jeremy sleeps with her sister Gloria (Isla Fisher), things get complicated and Christopher Walken ends up disappointed in them – which is far worse than simply being found out. The dynamic duo fall out as John pines for Claire and Jeremy keeps on keepin’ on with Gloria on the down low. Can there be a happy ending? Well obviously: this isn’t a bloomin’ drama.

Worst moment: Being hit on by the mother of the woman you love is never ideal. Then again, she’s Jane Seymour so it could be a LOT worse.

Moral of the story? Crash weddings; it’ll totally work out for the best.
