The story about Sir Alec Guinness you haven't heard anywhere else: at age 42 he experienced a miracle that changed his life and converted him to Catholicism.
“He made a deal with God: if God healed [his son] Matthew, he would allow his son to become Catholic if he wanted.
”Against all expectations (miraculously?), his son recovered! So Guinness and his wife enrolled him in a Jesuit school. A few years later, Guinness, his wife, and his son all converted to Catholicism.”
