Chicago area theatres do their part to provide fun or spooky entertainment. A show opening this weekend in north suburban Lake Forest is geared to families. A production out in the western suburbs is best for teens and older but is also interesting by the way it asks the audience to move with each scene through an old estate. Another show that will open in mid October at a Chicago theater, will leave audiences with perhaps a different understanding of a Shakespearean tragedy. Check them out this Halloween season.
