O’Reilly does bravura work both directing and portraying the hardened Screwballs. The veteran artist clearly knows the play all too well. Every scene, every character is crafted with a precise touch and he adds nuanced dimension in the most unexpected ways. The combined effect makes the production feel much bigger than the Irish Rep’s cramped stage might at first suggest. Kudos as well to set designer Charlie Corcoran and costumer Orla Long for capturing just the right tone in setting place and time.
