Jim Fredrick just let his colleagues know he’ll be exiting his post as EVP  of marketing at Sony Pictures’ Screen Gems. He left Warner Bros to take the Screen Gems job in late 2008, and oversaw campaigns for films that included  Obsessed, Death At A Funeral, Legion and Dear John. I’m told he and Screen Gems president Clint Culpepper didn’t mesh — but the exit is described as amicable.
