Sheryl Lee Ralph has been a staple of Black entertainment for decades. She played Deena Jones in the original Broadway production of “Dreamgirls,” and was in “Sister Act 2” alongside Lauryn Hill and Whoopi Goldberg. She’s currently starring in the new ABC sitcom “Abbott Elementary.” Her decades-long career gives her a unique perspective on how the industry has changed since she started—and how it hasn’t. “I think that, sometimes in order for institutions like Broadway to truly make room for others, you’ve got to break it down,” she tells The New Yorker’s Vinson Cunningham. “Because you’ve got to help people see things differently, outside of their own vision. And, even if it’s 20/20, it’s not perfect.”
