Amazon Studios’ is shaking up the leadership of its TV programming operations under Head of Television Vernan Sanders, I have learned. Marc Resteghini is stepping down as US/Global Head of Development, sources said. He is negotiating a producing deal with Amazon Studios. Nick Pepper, Head of Studio Creative Content, and Laura Lancaster, Head of Series, are expected to divvy up Resteghini’s responsibilities and co-run development and production of TV content, reporting to Sanders. MGM TV’s operations remain separate and do not factor into the current executive changes. A rep for Amazon Studios declined comment.
