The "Captain Marvel" star was in Chicago over the weekend for a comic book convention that brought together alums of the Marvel Cinematic Universe for a series of panels and meet-and-greets with fans. During one of her photo ops, one man, John Chambrone, used his brief time in the company of Larson to propose to his boyfriend, Richard Owens. "Y'all I was present for a proposal and I am CHANGED. Much love to the happy couple!!!!" Larson wrote, sharing photos captured during the proposal. On Facebook, Chambrone later called the encounter "the most epic moment of my life," and explained that he wrote a letter to Larson explaining what her Marvel character meant to him and his relationship. "The movie meant a lot to us and I was so glad that he now shares my passion for the greatest superhero in all the known universes," he said he wrote in the letter. Just days before the viral moment, Larson was on hand to accept an award at Variety's Power of Women luncheon for her accomplishments as a superhero off-screen and her work with the Equal Justice Initiative, a group that works to end mass incarceration and end excessive punishment in the United States. In her upcoming film "Just Mercy," Larson portrays Eva Ansley, one of the co-founders of the organization. &qRead More – Source
