CinemaBlend The Vampire Diaries and its spinoffs, The Originals and Legacies, with the latter still airing on The CW. Clearly not done within the world of bloodsucking drama, Plec is now heading to NBCUniversalâs streaming platform Peacock to start up a new vampire franchise. Julie Plec is set to adapt the Vampire Academy young adult book series, as written by Richelle Mead, for a scripted live-action drama for Peacock. The Vampire Diaries franchise co-creator and her longtime collaborator Marguerite MacIntyre will serve as co-showrunners on the series, and according to THR, the new project has already received a straight-to-series order.
