"Bruno Kirby (April 28, 1949 – August 14, 2006) was an American film and television actor. He was perhaps best known for his roles in the Hollywood films City Slickers and When Harry Met Sally...Kirby was born Bruno Giovanni Quidaciolu, Jr., in New York City, New York. His father was actor Bruce Kirby (born Bruno Giovanni Quidaciolu), and his brother, John Kirby, was a notable acting coach.Kirby was a popular character actor through the late 1980s and early '90s, although the frequency of his film appearances waned. Kirby's film debut was in the little-seen The Young Graduates (1971). Early television appearances included the series Room 222 and The Super, but it was his role in The Godfather Part II, as the young Pete Clemenza, that raised his profile in Hollywood. He can be glimpsed in the pilot episode of M*A*S*H, playing the character Boone, though he has no lines. In The Super, Kirby portrayed Richard Castellano's son. Coincidentally, Castellano appeared in The Godfather (1972) as hefty Pete Clemenza, a prominent member of the Corleone crime family, and Kirby subsequently played a younger version of Clemenza in the sequel, The Godfather Part II.In 1991, Kirby made his Broadway debut to great critical acclaim when he replaced Kevin Spacey in Neil Simon's Tony Award and Pulitzer Prize winning play Lost in Yonkers. In the last decade of his life, Kirby (and his unforgettable voice) had a last great success in the animated children's classic Stuart Little (1999), and was increasingly working on television. He starred as Barry Scheck in a 2000 CBS drama American Tragedy about the O.J. Simpson case. He played a paroled convict out for revenge in an episode of Homicide: Life on the Street. More recently, he played Phil Rubenstein in the HBO series Entourage.

In The Larry Sanders Show Bruno (as himself) gets 'bumped' in the last episode. The final episode of Season 3, part 1 of Entourage (entitled: ""Sorry, Ari"") is dedicated to Kirby's memory.Kirby married actress Lynn Sellers in 2004. He died on August 14, 2006, at age 57 in Los Angeles from complications related to leukemia. According to the Associated Press and other news reports, his widow stated that he had only recently been diagnosed with the disease.Kirby, like his character in This Is Spinal Tap, was a fanatical fan of Frank Sinatra. He was also deathly allergic to horses, and needed daily allergy shots on the set of City Slickers.In 2006, less than six months before his death, Kirby was invited to be a member of The Actors Studio."
