BBC Worldwide has teamed with Paul Marquess, former Head of Drama at Thames Television, to launch Cliffhanger Productions, focusing on making dramas for UK networks. BBC Worldwide has 25% of Cliffhanger while Marquess holds the rest. BBC Worldwide will be responsible for commercializing Cliffhanger’s content through its global sales and marketing network as well as local production bases. Marquess most recently was developing dramas for Endemol subsidiary Showrunner and has brought that company’s entire development slate with him to Cliffhanger. Donna Wiffen, Head of Production at Showrunner, joins Cliffhanger in the same role while Claire Fryer and Marianna Abbotts join as Development Producers.
