Wordstage Reader's Theatre in Arlington is not your ordinary theater company. But then it doesn't pretend to be, either.

The operative word in its name is "reader." In the current production, four talented actors give a harrowing live reading of the classic H.G. Wells tale "War of the Worlds," accompanied by the silhouettes of puppets. The readers do not move. They sit, dressed somberly in black and white.

You should know that Wordstage will not please everyone. While director Nancy Fees has put together talented group of actors--Jacquie Trople, Richard Glassco, Nick Penning and Robert Ashby--you should keep in mind that the performance they give is essentially a reading, not an action-packed theatrical drama. But it would be a mistake to dismiss the Wordstage production as anything less than true theater because of that.

Not surprisingly, its live reading format is particularly attractive to the blind because they are able to fully enjoy the performance.

Performances will be held at 8 p.m. April 22 and 23 at the Gunston Arts Center, 2700 South Lang St., Arlington. A $3 donation is requested at the door. For more information, call 558-2161. Other Events:
