Liberia (BT): Gerard Butler has swapped Hollywood for the kitchen as he became a volunteer for a charity which provides a daily meal for hundreds of thousands of the world’s poorest children. During a four-day trip to Liberia in Africa this month, the big screen star helped cooks prepare and serve meals to school pupils on behalf of Mary’s Meals.  Olympus Has Fallen actor Gerard loved the experience and said he has been inspired to get more involved with the charity , after he helped out in a school maths class, played football with children and danced with local villagers.
