Hysterically funny and heartfelt, this gross-out comedy, co-written and starring Kristen Wiig, shows real insight into what makes female friendships tick.

Wiig is singleton Annie, who goes into a neurotic tailspin when she agrees to be maid of honour at the wedding of her best friend (Maya Rudolph).

As Annie tries to outclass rich bridesmaid Rose Byrne, the farcical incidents multiply, most notably when food poisoning strikes at a dress fitting in a snooty bridal boutique.

Melissa McCarthy hits the bull’s-eye as a fellow bridesmaid, along with Ellie Kemper and Wendi McLendon-Covey, while Chris O’Dowd, as a traffic cop, and Matt Lucas, as Annie’s flatmate, are great in support.
