This extremely clichéd by-the-numbers comedy is about the most forgettable film of the year, and isn’t going to change anyones lives. However, there are many incredibly funny gags, both visual and scripted, whose humour will transcend age, and therefore make The Big Wedding a suitable cinema visit for families as large and different as that in the film. Robert DeNiro and Diane Keaton play the mother and father, long divorced with him in a stable relationship with Susan Sarandon. However, when adopted son Ben Barnes’ birth-mother comes to visit for his wedding to Amanda Seyfried, with her hardcore Catholicism intact, DeNiro and Keaton must pretend to still be married. The script’s mockery of religion and of its characters various flaws provides for great entertainment and charm, even if grit is utterly absent.
