When Judd Apatow wants ‘the big conversation’ it’s not just the comic-addressee who should get excited. Previous convos, with Steve Carell, Kirsten Wiig and Amy Schumer, in which the producer asked each talent: ‘have you any ideas?’ led to The 40-Year-Old Virgin, Bridesmaids and Trainwreck. His is an impressive eye for potential and one with an extraordinarily surefooted track record. Now Apatow has unearthed The Big Sick, the funniest rom-com of recent years, by mining the experience and skill of Kumail Nanjiani and Emily V. Gordon. He knows how to pick ‘em alright.
