Actor Aaron Pierre says stepping into the role of John Stewart in HBO Max's "Lanterns" is a dream come true, calling the Green Lantern hero relatable because "he wasn't born with superpowers," and that he leads with his heart. Pierre also revealed he pushed through a serious bicep injury to complete his final audition, saying there "was never an alternative" to giving his best. #aaronpierre #greenlantern #lanterns #JohnStewart #DCuniverse
