Danny Lloyd
Danny Lloyd became famous for his role of Danny Torrence in The Shining, but decided to put an end to his career as a child actor when he was 14. Later, he chose a very different profession far from the spotlight, becoming a biology professor and teaching at a community college. He still made a small appearance in the sequel to The Shining Doctor Sleep, but he wasn’t cast as the lead role this time.
