Jean Smart

After graduating from college, Smart began her career appearing in regional theater throughout the Pacific Northwest, including in Washington, Alaska, and Oregon. She performed with the Seattle Repertory Theater as well as the Oregon Shakespeare Festival in Ashland, Oregon. In the mid-1970s, she moved to New York City with college friend and fellow actress, Elizabeth Wingate (Lavery), and began working in Off-Broadway and professional regional productions.

In 1980, she appeared as Lady Macbeth at the Pittsburgh Public Theater opposite Tom Atkins as Macbeth and Keith Fowler as Macduff. In 1981, Smart was nominated for a Drama Desk Award for her performance in the Off-Broadway play Last Summer at Bluefish Cove. In February 1981, Smart appeared in a Broadway production of Piaf playing Marlene Dietrich, a role which she later reprised for the 1984 television version.

In addition to theater, Smart began working in television in several smaller to mid-size guest parts in the late 1970s and early 1980s, appearing on The Facts of Life, Alice, and Remington Steele among several others. According to Smart, after roles on the short-lived series Teachers Only and Reggie in 1983, "casting directors just decided I was funny. When that happens, you usually get pigeonholed, but I was fortunate. I got to move back and forth." The following year, she had a supporting part in the thriller Flashpoint (1984).

In 1985, Smart was cast in the starring role of Charlene Frazier Stillfield on the comedy series Designing Women, a role she played from the show's beginning in 1986 through its fifth season. After leaving Designing Women, her work mostly concentrated within made-for-television movies and supporting roles in films. Notably she portrayed serial killer Aileen Wuornos in the TV movie Overkill: The Aileen Wuornos Story (1992), followed by a supporting part in the black comedy Mistress (1992), opposite Robert De Niro and Eli Wallach. Critic Roger Ebert praised the film and called Smart's character portrayal "calculating".

The following year, she appeared in the family drama Homeward Bound: The Incredible Journey (1993), and as Ory Baxter in a television version of The Yearling (1994). She was then cast as Sally Brewton in the television miniseries Scarlett (1995), and appeared in a supporting role in The Brady Bunch Movie (1995). She also appeared in the television thriller film A Stranger In Town (1995) opposite Gregory Hines.

In 1995, Smart was cast as the lead in the comedy series High Society, which co-starred Mary McDonnell and ran for 13 episodes, followed by a role opposite Nancy McKeon in another short-lived CBS sitcom, Style & Substance. Other roles included a part in Neil Simon's The Odd Couple II (1998), and as Deborah Sloane in the drama Guinevere (1999). She had a lead role in the comedy Forever Fabulous (1999) as an aging beauty queen.

In 2000, Smart was cast as Lana Gardner in the critically acclaimed comedy series Frasier, acting opposite Kelsey Grammer, set in her home town of Seattle. She went on to win two Primetime Emmy Awards for Outstanding Guest Actress in a Comedy Series. Reflecting on the role, Smart said: "I had loved that role on Frasier so much, particularly that first episode. It's nice to get nominated and win for something you were particularly proud of. At the time I was a little bit snobby about doing guest parts. Based on what I don't know. It wasn't something I was seeking. But my agent said, 'You have to read this.' I thought it was hilarious and the show was brilliant so I didn't even hesitate. I remember when we did the table read with the rest of the cast we could hardly get through it we were laughing so hard."

The same year, she played in a Broadway revival production of The Man Who Came to Dinner, which earned her a Tony Award nomination. Soon after, she landed roles in several high-profile films including Sweet Home Alabama (2002), playing the mother-in-law of Reese Witherspoon, and in the comedy Bringing Down The House (2002), opposite Queen Latifah.

She also had a supporting role in David O. Russell's I Heart Huckabees (2004).

In January 2006, Smart joined the cast of the Fox series 24, playing the mentally unstable First Lady of the United States, Martha Logan, to actor Gregory Itzin's President Charles Logan. She received back-to-back Emmy nominations for Outstanding Supporting Actress in a Drama Series and Outstanding Guest Actress in a Drama for the role in 2006 and 2007.

Smart plays as Laurie Blake formerly the second Silk Spectre, who has since become an FBI agent and member of the Anti-Vigilante Task Force. Smart starred alongside Regina King, Jeremy Irons, Yahya Abdul-Mateen II and Louis Gossett Jr. Smart's performance was singled out by critics including Eric Deggans of NPR who described her performance as "compelling" and "the always-excellent Jean Smart [playing] a cynical, heroically-damaged middle-aged version of Laurie Juspecyk." The series received critical acclaim winning 11 Primetime Emmy Awards including Outstanding Limited Series. Smart herself was nominated for Primetime Emmy Award for Outstanding Supporting Actress in a Limited Series or Movie and received the Critics' Choice Television Award for Best Supporting Actress in a Drama Series for her performance.

In 2021, Smart has appeared in the seven episode HBO crime drama limited series Mare of Easttown set in a small town in Pennsylvania. The series stars Kate Winslet as a grizzled detective with a supporting cast which includes Guy Pearce, Julianne Nicholson, and Evan Peters. Her role as Winslet's mother has earned her critical acclaim with Jackson McHenry of Variety writing, "It's one of those essential truths of TV, as Watchmen and Legion displayed recently, that if you need a tough-as-nails broad, you hire Jean Smart. Smart has the voice and the timing to play a stern matriarch, and whenever she's onscreen in Mare of Easttown, she wrenches away the spotlight like she's grabbing a juice box."

She also stars as the lead in the HBO Max dark comedy series Hacks (2021) playing a legendary Las Vegas comedy diva looking to appeal to a younger audience. USA Today declared Smart, at the age of 69, "The Queen of HBO", after appearing in Watchmen, Mare of Easttown and now Hacks. Glen Weldon of NPR praised Smart's performance in his review writing, "I don't know if the role of Deborah Vance was written for Smart, but she certainly makes it seem like it was...Smart's also convincing as a standup, performing Deborah's vaguely hokey routines with a naturalistic flair as if she was born to it." She won two consecutive Primetime Emmy Awards for Outstanding Lead Actress in a Comedy Series (2021 and 2022). She won the Primetime Emmy Award for Outstanding Lead Actress in a Comedy Series again in 2024.
