SPECIAL FROM Next Avenue By Sue Campbell No one expected a movie about down-on-their-luck retirees — some broke, some heart-broken — to become a box office hit. But with star power from Maggie Smith, Judi Dench, Bill Nighy, Lillete Dubey and Celia Imrie to add dimension and depth, it did. Now, the sequel, The Second Best Exotic Marigold Hotel, follows the group living in India at a rundown senior residence as they settle in and their relationships change.
