Dan Telfer’s play, a world premiere from Theater Oobleck, is inspired by the mythic monster from Beowulf. More than just a facile reversal of the original, with Beowulf as blustering warrior and Grendel as misunderstood misfit, this is a kind of comic-mythic cosmology of evil, exploring questions of time, mortality, and what it means to be God’s outcast. Colm O’Reilly is excellent in the title role–part Caliban, part Kramden. (ZT) a North theater, 7 PM.

The Still Point Theatre Collective presents Teresa Weed’s new play based on the life and work of Trappist monk and radical political essayist Thomas Merton. This placid, overlong, dry-as-dust assemblage of set pieces fails to capture the essence of a man who was both removed from the world and deeply engaged with it; it feels stilted and lifeless in a way that Merton’s work never does. (ZT) a North theater, 3 PM.
