At left, The Real Thing's playwright Tom Stoppard celebrates the Broadway revival of his play April 17. At right, mother and daughter Broadway team, Jennifer Ehle (starring in The Real Thing) and Rosemary Harris (now opposite Lauren Bacall in Waiting in the Wings).

Stephen Dillane and Ehle star in the revival at the Barrymore Theatre.
