Chicago's Redmoon Theatre invokes silent film comedian Buster Keaton, Belgian artist Rene Magritte and the biblical story of Abraham and Isaac in its latest production, Unbinding Isaac. The play, written and directed by Redmoon artistic director Jim Lasko, will run at the Steppenwolf Theatre Company's Studio space, April 5-May 6, officially opening April 12. Lasko wrote his latest work with an eye toward examining the mystery of faith. Abraham was, of course, instructed by God to sacrifice his son Isaac, only to have his murderous hand stayed at the last minute by an angel. Here, Isaac goes on to encounter various characters and events, which he handles with the nonplussed aplomb of Keaton. The action of the play takes place in a human-sized puppet theatre designed by Stephanie Nelson, the structure equipped with trap doors and Magritte-like images.

Tickets are $15-$22. Steppenwolf's Studio space is located at 1650 N. Halsted St. For more information, call (312) 335-1650.
