Magic and musical theater, when combined, generally earn great acclaim, whether the show in question is Wicked, Cinderella, or any of the many iterations of Peter Pan that have graced stages in recent years. Signature Theatre, purveyors of the more realistic musicals of Stephen Sondheim, hopes to cash in on this fantastical trend with its latest offering, the premiere of Anton Dudley and Brian Feinstein’s Girlstar. Tagged with the slightly unappealing line of “The Voice meets Maleficent,” the musical follows possessed record producer Daniella, who finds her next pop ingenue in a long-lost niece, Tina. Transforming Tina into the next Selena Gomez proves relatively easy from a physical standpoint, but the emotional transformation doesn’t go as well. Dudley and Feinstein encourage the audience to question the acceptable limits one should go to in order to become a star while keeping the subject matter light enough for the tween audiences Signature is hoping to court. Dubious theatergoers can rest assured that, while magical, the content is far from Disneyfied. The play runs Oct. 13 to Nov. 15 at Signature Theatre, 4200 Campbell Ave., Arlington. $40–$96.
