Huntington digs for spring

A new musical based on the classic Alec Guinness film "King Hearts and Coronets" highlights the Huntington Theatre Company's 2006 Breaking Ground Festival of new-play readings. Campbell Scott, Denis O'Hare and Michael T. Weiss top the list of name actors in the event at the BCA's Calderwood Pavilion April 6-9. Plays in development by Theresa Rebeck, Noah Haidle and Ronan Noone are also on the sked. The "suggested donation" at the door is just $10 but reservations are recommended. Call 617-266-0800.
