After learning that his son Michael Douglas is cancer-free, Kirk Douglas acknowledged the power of the Almighty.
“I believe God answers all prayers,” the 94-year-old screen icon tells PEOPLE. “Sometimes his answer is no, but not this time!”
Douglas says he cried tears of joy when Michael told him the news that the radiation and chemo got rid of the tumor in his throat. Describing his relief, the patriarch adds wryly, “I immediately felt years younger. Not a day over 85.”
