Ryan Reynolds really cares about his fans.The star did his part to help make a terminally ill child's dream come true by calling the young Marvel superfan from the set of Deadpool 2. When 5-year-old Daniel Downing was diagnosed with a particularly aggressive form of brain cancer earlier this month, his parents set about trying to arrange a phone call from the Deadpool star to help raise their son's spirits. Reynolds was more than happy to speak with the young fan.
