Poor J.M. Barrie hasn’t had an easy time of it in the 21st century, with the notable exception of revivals of one-acts at the Mint Theater. The 2015 musical Finding Neverland, based on a film, focused on the dramatist’s struggle to find success after failure and the triumphant creation of Peter Pan, his classic 1904 play about the boy who won’t grow up—a play that, by the way, most of Finding Neverland’s audience had probably never seen, since nobody actually stages it. It’s known primarily through the musicalized version from the 1950s that starred Mary Martin, although the Royal National Theatre’s 1997 production, with Peter played by Daniel Evans, now artistic director of the Chichester Festival, and Ian McKellen as Captain Hook, showed the original is still a viable and glorious work.
