Acting couple Eli Wallach and Anne Jackson may already be theatre royalty, but until June 14 they can not by rights call themselves Brooklyn royalty. On that day, the actors will be dubbed King and Queen of the borough which produced Wallach. (Jackson is a Pennsylvania girl, but was raised in Brooklyn.) The event is the cap of the day-long Welcome Back to Brooklyn Homecoming Festival.

Both Wallach and Jackson are currently gracing the New York stage: Wallach in Jeff Baron's Visiting Mr. Green at the Union Square Theatre; and Jackson in Arthur Miller's latest, Mr. Peters' Connections, at the Signature Theatre Company. Both have frequently appeared on stage frequently, in such plays as Cafe Crown, Rhinoceros, and This Property Is Condemned -- the production where they met. Wallach was born in Brooklyn on Dec. 7, 1915 and raised in the Red Hook neighborhood.

The festival takes place from noon to 6 PM, rain or shine, at Grand Army Plaza, and features continuous entertainment on three stages. Most of the attractions are free. For information, call (718) 855-7882, ext. 54.

Brooklyn Kings and Queens of the past include Ben Vereen, Vincent Gardenia, Paul Sorvino, and Lainie Kazan.
