New Group artistic director Scott Elliott will stage the American premiere of the work scheduled to begin May 4 and open May 18 for a run at The Acorn @ Theatre Row through June 27. "On the barren, diamond-diving coast of South Africa, Johan and Thami, an ex-cop and a gardener from starkly contrasting backgrounds, maintain a beachfront guest lodge during the off-season while looking for a way out," reads a show description. "When Smith, a retired businessman, shows up one foggy night, the two men think they've found an ideal investor for their scheme to buy into a government-run mining concession. Soon, these rootless men find themselves in a power struggle fueled by greed, desperation and entitlement."

Bryggman, a two-time Tony Award nominee (for Proof and Picnic) has also been seen on Broadway in Twelve Angry Men and Festen and Off-Broadway in Occupant. He will be joined onstage by Lansbury (Hedda Gabler, Major Barbara) and newcomer Savane (star of film "Goodbye Solo").

The play was first produced by Cape Town, South Africa's New Africa Theatre in 2005. The Off-Broadway design team includes Derek McLane (set), Eric Becker (costume), Jason Lyons (lighting) and Shane Rettig (sound).

Groundswell replaces the rescheduled production of Seth Rosenfeld's Handball. The New Group opened its season with Kevin Elyot's Mouth to Mouth and recently presented Eugene O'Neill's Mourning Becomes Electra.
