If you’ve got pre-teen kids and they haven’t discovered Wimpy Kid, now is your chance to introduce them to something they will love. Jeff Kinney’s books – the half cartoon, half written diaries of unpopular school kid Greg Heffley – are huge in the States, but have more of a cult following here. But those who know the books and the first film are obsessed, and have been counting the minutes for movie number two: Wimpy Kid 2, Roderick Rules. So treat them to the BFI’s Wimpy Kid day this Sunday. They’ll be able to create their own Greg Heffley diary at the free workshop at 11.30 am, and then be the first to see the film at the special preview screening at 1.30pm. Book now to avoid disappointment. Further good news: this is a movie that you’ll enjoy almost as much as them. Never mind Greg, we’re obsessed with Roderick.
