It’s definitely slim pickings on DVD and Blu-ray this week with even fewer new releases than usual, but at least there’s a power trio of family films that includes Steven Spielberg’s War Horse, Cameron Crowe’s We Bought a Zoo and the acclaimed documentary Being Elmo: A Puppeteer’s Journey. Beyond that we’ve also got Paddy Considine’s bleak directorial debut Tyrannosaur and the first season of Chris Elliott’s Adult Swim series Eagleheart, which I have heard good things about. As for Blu-ray, it’s all about Roman Polanski’s Chinatown and Madonna: Truth or Dare, a movie that remains to this day one of the highest grossing documentaries of all time. What will you be buying or renting this week? Check out the full list of releases after the jump.
