Corin Redgrave plays a tough guy in Broadway's Not About Nightingales, but he's also tough off stage.

The Tony Award-nominated Redgrave tripped over a piece of the scenery in the final moments of the May 12 matinee of the Tennessee Williams drama, set in a cruelly-managed American prison. He suffered cuts to his face and lip.

The stark set, designed by Tony-nominated Richard Hoover, is particularly cruel: It's mostly metal.

The performance continued, however, and Redgrave went on for the evening show and the May 13 performance, with stitches in his lip and face. He is not expected to miss shows at Circle in the Square Theatre, according to a spokesperson. He will also perform, as scheduled, Oscar Wilde's De Profundis for an Actors Fund benefit at Circle in the Square May 16.

In Nightingales, an early, previously-unproduced 1938 work by Williams, Redgrave plays Boss Whalen, the venal, Southern-fried prison warden whose thirst for liquor, punishment and carnality is not easily slaked. The Broadway premiere staging, an extension of stagings that played the Royal National Theatre in London and the Alley Theatre in Houston, earned six Tony nominations: Best Leading Actor in a Play, Best Featured Actor in a Play (Finbar Lynch), Best Play, Best Scenic Design (Richard Hoover), Best Lighting Design (Chris Parry) and Best Director (Trevor Nunn).
