It may be related to diminishing attention spans, or the influence of speed-dialing or instant messaging, but whatever the cause, the popularity of the 10-minute play speaks directly and metaphorically to our own time. In two volumes, Michael Bigelow Dixon and Liz Engelman have compiled a intriguing group of short works from such sources as the Guthrie Theatre in Minneapolis, the Actors Theatre of Louisville, the Cincinnati Shakespeare Festival and the Triangle Theater in New York City. The plays cover a wide variety of subject matter, locales, styles and characters. The two volumes (from Smith and Kraus) are The Best Ten-Minute Plays for Two Actors [ISBN 1-57525-336-4] and The Best Ten-Minute Plays for Three or More Actors. Each Costs $19.95 [ISBN 1-57525-337-2].
