Movie star Scarlett Johansson made a very successful Broadway debut in 2010, so successful that she won a Tony Award for her work in Arthur Miller’s “A View from the Bridge.” Three years later, she’s back on Broadway in a much more substantive role as Margaret, or “Maggie the Cat” (as the character is more often referred to), in Tennessee Williams' “Cat on a Hot Tin Roof" at the Richard Rodgers Theatre.
