The audience, which included most of the critics from the major New York City-area newspapers, heard a grinding noise at 10:03 PM during the Act Two song "Nothing Stops Another Day." Conductor David Holcenberg silenced his cast and his orchestra, and production stage manager Ira Mont was heard over the sound system announcing a delay due to a technical problem. The curtain was dropped.

The pop musical based on the 1990 romantic-thriller film will officially open April 23. The Thursday audience included reviewers from the New York Times, the New York Post, Newsday, New York Daily News and other media outlets. Critics are usually forgiving of technical mishaps; the interruption probably won't impact their assessment of the quality of Ghost.

Playbill has sought a statement about the nature of the technical problem. Over at the tech-heavy Spider-Man Turn Off the Dark, at the Foxwoods Theatre, reports of mid-show stoppages were common during previews (and sometimes during the regular run of the show).

A handful of audience members left during the unexpected break at Ghost on Thursday, but most stayed to see the conclusion of the plot — and the resumption of the show's arresting video walls, which are in constant motion during the two-and-a-half-hour experience.

When the curtain came back up by 10:30, game actress Caissie Levy, as Molly, continued "Nothing Stops Another Day," apparently where she left off, in mid-song, to cheers and applause. "I'm Outta Here," an animation-spiked production number for actress Da'Vine Joy Randolph, who plays vivacious medium Oda Mae Brown, followed. The rest of the show, directed by Tony Award winner Matthew Warchus, went off seemingly without a hitch, leading to a standing ovation at 10:55 PM.

Wouldn't you stand, too? You don't want to make the ghosts of the Lunt-Fontanne angry.
