PITTSFIELD -- Four-time Tony Award nominee Gregg Edelman and Emmy Award winner and two-time Tony Award nominee Penny Fuller are joining Maureen O’Flynn, Kate Baldwin and Graham Rowat in Berkshire Theatre Group’s production of Stephen Sondheim’s "A Little Night Music," June 30 through July 19 at BTG’s Colonial Theatre.

Edelman will play the leading role of Fredrik Egerman and Fuller will play the pivotal role of Madame Armfeldt in BTG’s summer musical. Ethan Heard, who directed BTG’s 2013 hit murder mystery "The Cat and the Canary," will direct.

Since his Broadway debut in the original "Evita," Edelman has starred on Broadway in "City of Angels," "1776," "Into the Woods," "Wonderful Town," "Cabaret" and last season’s revival of "The Mystery of Edwin Drood." His regional theater credits include productions at George Street Playhouse in New Brunswick, N.J., and Drury Lane Theater in Chicago.

On television he’s been seen in "Hack," "The Good Wife," "Blue Bloods," "Law and Order," "Law and Order: SVU," "Law and Order: Criminal Intent" and heard as the voice of the peanut M&M.

Edelman has performed in concert with the Boston Pops, Detroit Symphony, New York Pops, and the Philadelphia and Chicago Pops.

Fuller began her Broadway career in Neil Simon’s "Barefoot in the Park," three Shakespeare in the Park productions, and the musicals "Rex," "Cabaret" and "Applause," for which her performance as Eve Harrington earned her a Tony Award nomination.

She won an Emmy Award for her work in ABC’s "The Elephant Man."

Her recent Broadway appearances include Horton Foote’s "Dividing the Estate," Neil Simon’s "The Dinner Party" (Tony nomination) and William Finn’s "A New Brain." Her regional credits include "The Seagull," "A Delicate Balance," "A Little Night Music," "Do I Hear a Waltz?" and "An American Daughter."

Fuller has just begun a new phase of her career as a cabaret artist in New York clubs and theaters. She has collaborated with cabaret director Barry Kleinbort on "Thirteen Things About Ed Carpoletti," a solo musical with book, music and lyrics by Kleinbort, performed off-Broadway at 59E59 Theaters and scheduled for Merrimack Repertory in Lowell in December.
