Film and television
While in Los Angeles waiting to receive a Tony for her appearance in Sweet Charity in 1985, Neuwirth auditioned for the role of Dr. Lilith Sternin in the television series Cheers. At the time, Neuwirth was not interested in doing television work and her character was initially planned to be in only one episode of the series. However, the writers enjoyed writing her dialogue so much that she was written into more episodes of the show, eventually making her one of the series' recurring actors.
Neuwirth's character Lilith eventually married Frasier Crane (Kelsey Grammer). From the fourth to the ninth season, Neuwirth portrayed Lilith in a regular recurring role, and she appeared on the show as a main star for both seasons ten and eleven. Like Kelsey Grammer when he started on the show as Frasier, she was not immediately given star billing in the opening credits but in the end credits for seasons eight and nine, appearing in the opening credits with her own portrait in seasons ten and eleven. She won two Emmy Awards for Outstanding Supporting Actress in a Comedy Series for the role, in 1990 and 1991. The character also made an appearance in the series Wings and in twelve episodes of the Cheers spin-off Frasier, which earned her a 1995 Emmy Award nomination for Outstanding Guest Actress in a Comedy Series at the 47th Primetime Emmy Awards. She left Cheers in 1993 to go back to her career in dancing, but would make more television appearances in other shows and commercials.
Neuwirth's dip into the film industry began in 1989 with small roles in films such as Say Anything... (1989), Pacific Heights (1990), and Penny Ante (1990). In 1990 she started doing supporting roles in films including Green Card (1990), Bugsy (1991), and Malice (1993), in all of which she received acclaim from critics for her performances. Her first lead role came in 1993, when she played Margaret, a married woman attracted to her neighbor Wesley (Will Patton), in the psychological thriller comedy film The Paint Job (also released as Painted Heart). Her other credits include Jumanji, Summer of Sam, Liberty Heights, An Extremely Goofy Movie, The Adventures of Pinocchio, Tadpole, The Associate, How to Lose a Guy in 10 Days, The Big Bounce, Le Divorce, The Faculty, and Woody Allen's Celebrity. In 1996, she starred in a pilot for a TV series called Dear Diary for ABC which was not picked up. The producers had it edited slightly and put into a single theater for a single weekend in November 1996, and it became one of only two TV pilots to be nominated for an Oscar and, at the 69th Academy Awards, the only one to win.
Other small-screen credits include a guest appearance in the second season of NewsRadio, a small role on The Adventures of Pete and Pete (episode: "The Call"), Deadline (2000), Hack (2003), Law & Order: Trial by Jury (2005) as ADA Tracey Kibre, Law & Order: Special Victims Unit (1999) as Nina Laszlo, a modeling agent/suspect, the miniseries Wild Palms, and the fourth season Star Trek: The Next Generation episode "First Contact" as Lanel.
Neuwirth appeared as herself in episodes of Will & Grace, Strangers with Candy and Celebrity Jeopardy!. In 2009, she co-starred as Ms. Lynn Kraft in the remake of Fame. She had a recurring role as Caroline Taylor, the literary editor of Jonathan Ames (Jason Schwartzman), on the HBO series Bored to Death. She also had a recurring role on Blue Bloods.
Neuwirth starred as Nadine Tolliver in the 2014 CBS political drama Madam Secretary. In October 2017, Neuwirth announced her decision to leave the series after four seasons. No reason was given. She later reprised the role of Nora Shepherd in Jumanji: The Next Level in 2019; the film grossed $800 million worldwide and received positive reviews from critics.
