Jeremy Irons’ son Max, 27, is striking out on his own with “The Host” from “Twilight” creator Stephenie Meyer. “He gives me advice on the business side of things,” said Irons of his famous dad, “But yes, I want to enter a stage of my career where my name isn’t prefaced with ‘son of Jeremy Irons.’ ” At a Cinema Society/Jaeger-LeCoultre-sponsored after-party for the film at Jimmy were Joshua Jackson, Dylan McDermott, Patti Smith and Gabourey Sidibe.
