From out of nowhere, 28-year-old singer-actor Jessie Mueller arrived on Broadway last season in the ill-fated “On a Clear Day You Can See Forever” revival, pocketed all the reviews, and walked away with the show. She’s been busy ever since, performing in concerts around New York City and playing Cinderella in Shakespeare in the Park’s production of “Into the Woods” over the summer. Next up, she’ll remind everyone just how talented she is in the revival of “The Mystery of Edwin Drood.” (Photo by Paul Kolnick)
