The Heiress headliners Jessica Chastain and Dan Stevens headed to TV’s Good Morning America on November 8, and the duo seemed more like old pals than new co-stars. Although both actors have already experienced their fair share of success (Chastain is an Oscar nominee for The Help and Stevens is best known as Downton Abbey heartthrob Matthew Crawley), the pair has been bonding over making their Broadway debuts together. Stevens even joked that he learned his “perfect” American accent from Chastain.
