EXCLUSIVE: On lunch break Thursday in the first day of shooting of his first U.S.-set film Bones & All, director Luca Guadagnino talked about seizing the chance to reunite with Call Me By Your Name cohorts Timothée Chalamet and Michael Stuhlbarg, latter of whom he added to cast along with André Holland, Jessica Harper, Chloe Sevigny, Francesca Scorsese (the Guadanino-created HBO series We Are Who We Are), and David Gordon-Green — yes, the Halloween director.
