Olivia Thirlby is the eye at the centre of a very sexy storm in this warm, hysterically funny dramedy       When her young filmmaker breezes into town, she comes riding a wave of effortless sexiness, which carries her through a net of passions-gone-wild as men queue up to fall at her feet      　　Though the film could’ve done with more depth, it wisely plays down the angst and is content to sit back as sparks fly between its central players – including Rosemarie DeWitt and John Krasinski
