Lucie Arnaz begins performances as opera diva Maria Callas in New Hampshire's Seacoast Repertory Theatre production of Master Class April 22. Terrence McNally's play runs through May 23 at the Rep's theatre in Portsmouth. Arnaz, the daughter of famous I Love Lucy! pair, Lucy and Desi Arnaz, has appeared on Broadway several times, most recently as Bella in Neil Simon's Lost in Yonkers. Other New York credits include Seesaw, They're Playing Our Song and Grace and Glorie with Estelle Parsons. She has toured with Whose Life is it Anyway?, I Do!

Along with an Emmy (which she won for the 1993 documentary, "Lucy & Desi: A Home Movie"), Arnaz has been honored with a Los Angeles Drama Critic's Circle Award, Theatre World Award, Outer Critic's Circle Award and Chicago's Sarah Siddons Award.

Master Class takes place in a fictionalized master class at Julliard where famed opera diva Maria Callas, late in her career, fluctuates between berating the students who are performing for her and sharing memories from her career with the audience. Other plays by Terrence McNally include the opera-Callas related Lisbon Traviata as well as Love! Valour! Compassion!, Frankie and Johnny in the Claire de Lune and Corpus Christi.

Tickets for Master Class are $20-$17. For reservations, call (603) 433-4472. The Seacoast Repertory Theatre is located at 125 Bow Street.
