On the 400th anniversary of William Shakespeare’s death, we look at the ways his work continues to change and adapt to the culture we live in. In the 19th century, Shakespeare’s work got caught up in minstrel shows — and African-American actors are still struggling to claim the Bard as their own. Also, we find out how a father-son team is changing the way Shakespeare sounds by bringing back his original pronunciation. And we go inside the pioneering immersive theater experience “Sleep No More,” which might be the longest-running Shakespeare adaptation ever.
