Richard Foreman's latest production, Bad Boy Nietzsche, will end its long run on April 30. The show began performances Jan. 27 and officially opened Feb. 8. All performances through April 30 are sold out, but the box office is taking reservations for the waiting list. Call (212) 533-4650.

The new work focuses on an encounter between the philosopher and a dray horse being beaten -- a moment that, according to production notes, sent Nietzsche hurdling into madness. The production will star two actors found in Foreman's Hotel Paradise last year, Juliana Francis and Gary Wilmes (as Nietzsche). Francis has also been seen in John Jahnke's Lola Montez in Bavaria (in the title role), while Wilmes practiced his deadpan in Richard Maxwell's House. Also in the cast are Kevin Hurley and Sarah Lilley.

Foreman's many plays include Pearls for Pigs, Benita Canova and What Did He See?, most of which featured, in production, Foreman's trademark cluttered set designs, festooned with mirrors reflecting the audience and strings stretched across the playing area.

Tickets are $15. The Ontological Theatre is located at 131 E. 10th St. In Manhattan.
