EXCLUSIVE: There is a change at the helm of Fox’s comedy department. Julia Franz is stepping down as SVP and head of comedy for Fox Entertainment after three years. She will be succeeded in the role by former 20th Television head of comedy development Cheryl Dolins who will be based in Los Angeles, reporting to Fox Entertainment President Michael Thorn. The changeover had been in the works for awhile and is not related to Fox Entertainment CEO Charlie Collier’s surprise exit on Thursday to join Roku.
