In "Dark Water/Death in Heaven," theatergoers can relive when the Doctor (Peter Capaldi) comes face-to-face with the mysterious Missy (short for the Mistress) as the villainous Cybermen take over the streets of London. The episode will be followed by "The Doctor's Meditation," a prequel scene to series' Season 9 premiere, which airs Sept. 19 on BBC America. Rounding out the event will be an interview with Capaldi and co-star Jenna Coleman hosted by actor Wil Wheaton.
