UNIVERSAL CITY, Calif. -- January 6, 2012 -- Three-time Grammy Award winner, two-time Emmy Award winner and Tony Award nominee Harry Connick Jr. will have a multi-episode, guest-starring turn on the Wolf Films/NBC drama “Law & Order: Special Victims Unit” (Wednesdays, 10-11 p.m. ET). Connick will guest-star as Executive ADA David Haden, a dedicated, straight-shooting prosecutor who is assigned a case with Detective Benson (Mariska Hargitay). Although Benson is at first wary of Haden, they are both surprised to find they work well together. As the case develops, so does their relationship. Connick’s first episode will air January 18. “This is a home run on so many levels,” said Hargitay. “The show is very fortunate to have Harry's extraordinary talent, and I'm lucky because I get to work with my friend. I think Olivia couldn't have asked for a better companion to take her through a new stage in her life and career.” A star in music, theater, film and television, Connick recently won his second Emmy for musical direction of his live concert television special, “Harry Connick Jr. in Concert on Broadway.” He currently is starring on Broadway in the musical “On a Clear Day You Can See Forever” about which USA Today said: “Harry Connick Jr. has never sung or acted more powerfully.” The musical is directed by Tony Award-winner Michael Mayer, who also is the director of NBC’s upcoming Broadway-themed drama “Smash.” This year Connick starred in the hit film “Dolphin Tale” which debuted at #1 at the box office with Ashley Judd, Morgan Freeman and Kris Kristofferson. He also added author to his credentials with “The Happy Elf,” his beloved song and children’s Christmas stage musical turned into a keepsake children’s book with an accompanying instrumental jazz CD released by Marsalis Music. On television, Connick is best remembered as Dr. Leo Markus on NBC’s “Will and Grace.” A proud New Orleans native, Connick and longtime friend Branford Marsalis opened the Ellis Marsalis Center for Music in The Musicians’ Village in the Ninth Ward of New Orleans last summer, in conjunction with Habitat for Humanity. From music to dance, theater to film, the goal of the Center is to harness the exceptional talents of the residents and students of the surrounding Musicians’ Village in a collective effort that will provide an invaluable resource to New Orleans. “Law & Order: SVU” is a Wolf Films production in association with Universal Television. Dick Wolf, Warren Leight and Peter Jankowski are executive producers.
