In a statement to Deadline, Casey Bloys, president of programming for HBO, said: “David has been a valued member of the HBO family for 10 years and worked on some of our finest shows. We look forward to working with him as a producer on projects in the years to come. We’re thrilled that Francesca will step up to head of drama programming.”
