Broadway may be getting Wait Until Dark this spring, but John Pielmeier's thriller Voices in the Dark won't happen until fall 1998, according to producer Ben Sprecher (reached Mar. 3).

Originally targeted for April, Voices had to postpone because star Gates McFadden, who played Dr. Beverly Crusher on TV's "Star Trek: The Next Generation," is busy shooting the Next Generation movie. His Voices co-stars will be Jonathan Hogan, Robert Petkoff, Peter Bartlett and two other actors.

Christopher Ashley will direct Voices in the Dark, which tells of a radio psychologist trapped with a psycho in a snow-bound house. The play was mounted by Pielmeier himself (author of Agnes of God) back in October 1994 at Seattle's A Contemporary Theatre. Says Sprecher, "It'll be fabulous. A big hit."

Designing the Broadway Voices, which hasn't yet selected a theatre, will be David Gallo (set) and Donald Holder (lighting).

Back in November 1997, Sprecher told the NY Times Voices was "a thriller for the 90's...It's not Wait Until Dark." The latter thriller stars Marisa Tomei and Quentin Tarantino and starts previews March 27 for a limited run at the Brooks Atkinson Theatre. Sprecher also told the Times Voices has been targeting Broadway because he expected all the Off-Broadway theatres he operates to be booked.

Pielmeier's other works include Willi, which he appeared in at Seattle's ACT in 1991, Steeple Chase and Impassioned Embraces.
