The Orphan’s Home Cycle (Signature Theatre, 555 W. 42, closes May 8). Horton Foote’s three-part condensation of his great nine-play cycle about American family life in the first part of the twentieth century has just been extended through May 8. This means that there will now be five single-day marathon presentations of the complete cycle, on February 6 and 27, March 6, April 3, and May 8. Having seen all three parts separately, I suspect that seeing them in a single day is likely to be the best way to experience this not-to-be-missed theatrical event.
