At 16, Robert Bruce jumped out of his bedroom window to join the circus. He must've loved it because at 81, he is still entertaining families as one of the world's oldest circus clowns. Just to add to his unique life, no one was more surprised than him when he found out he was going to be a father again at 73. But like everything he does in life, Robert took on fatherhood in his seventies with positivity, fun and a youthful exuberance. A Hollywood film is now being made about Robert's remarkable life.
