Lonergan directs the piece which will officially open June 7 at The Irene Diamond Stage.

The cast includes John Pankow, Anthony Arkin, Heather Burns, Tate Donovan, Halley Feiffer, Kevin Geer, Josh Hamilton and C.J. Wilson. Signature bills Medieval Play this way: "Two French mercenary knights set out on a quest for relative moral redemption against the classic comic background of late 14th-century ecclesiastical politics. A story of friendship, love, noble feats of arms, indiscriminate brutality, the progressive refinement of medieval table manners and the general decline of the chivalric ideal at the onset of the Great Papal Schism of 1378."

Here's a look at the production:
