EXCLUSIVE: Microsoft’s nascent unit run by Nancy Tellem continues to staff up, with Albert Page signing on as VP Creative. Before joining Xbox Entertainment Studios, he was SVP Production and Development at Mandeville Films, where he developed films including The Proposal and Best Picture Oscar nominee The Fighter. Page’s résumé also includes a stint at The Alchemist Transmedia Company, where he developed global brand strategies and multiplatform original content for clients including Coca-Cola. Based in L.A., he will report to Lydia Antonini, SVP Creative for Xbox Entertainment Studios. The new division last month hired Elan Lee as Chief Design Officer. Two weeks before that, Microsoft CEO Steve Ballmer came to town to get TV moguls and agents up to speed on the new Xbox One’s capabilities.
