Ever adept at attracting top-line talent, Graham welcomes Thor star Chris Hemsworth and director Ron Howard (Apollo 13) to his sofa. The duo plug cinematic epic In the Heart of the Sea, based on Nathaniel Philbrick's account of the real-life whaling expedition that inspired Moby-Dick. Lily Tomlin, tipped for an Oscar for her role in Grandma, also guests, as does comedian Kevin Bridges. Blake and Dame Shirley Bassey, who have collaborated on a new Christmas single, provide the musical entertainment.
