ITV Studios UK has moved quickly to fill the Managing Director post that will be vacated by Denise O’Donoghue at the end of 2014. Julian Bellamy, who is currently Discovery Networks International Creative Director and Head of Commissioning, will take over from O’Donoghue later this year, ITV said today. TV veteran O’Donoghue has been MD at ITV Studios UK for four years and will remain on the board of the country’s largest commercial production company after stepping down. Bellamy has spent three years at Discovery, running production and development across 200 countries, with commissioning teams in five international bases. Prior to DNI, he ran the UK’s Channel 4, managing over 2,000 hours of original programming per year including Undercover Boss, My Big Fat Gypsy Wedding and One Born Every Minute. He previously held executive posts at the BBC and E4. ITV Studios’ titles include Mr Selfridge, Agatha Christie’s Poirot, Breathless and the upcoming Thunderbirds Are Go! The production arm of ITV is one of the biggest growth areas for the group, which has been on a U.S. and UK shopping spree in the past 18 months.
