Margaret Sullivan Was a Mentor
Remember how Margaret Sullavan married someone else, breaking Stewart’s heart? Despite that, they were an incredible team. She helped him shine and brought out the best in him. And somehow, he managed to get over the heartbreak…

Back in the early days of his acting career, Stewart was kind of shy and awkward. Executives weren’t sure if they should take a chance on him. But Sullavan believed in him and made sure he got roles alongside her. She even coached him on how to improve his acting skills. Thanks to her, Stewart went from being just another actor to a real star on the big screen.
