Her last film was Anger Management (2003), starring Adam Sandler and Jack Nicholson (which was released only a month following her death and paid tribute to her in the end credits).
Thigpen was perhaps best known for playing Luna in the television show, Bear in the Big Blue House as well as “The Chief” of the ACME Detective Agency in the long-running PBS children’s geography game show Where in the World Is Carmen Sandiego?, which involves both education and comedy, and, on occasion, musical performance. She remained The Chief in the successor show, Where in Time is Carmen Sandiego?, but of ACME Time Net.
She also appeared in many other television series during her career, most notably in a recurring role as Grace Keefer on the ABC daytime drama All My Children and a supporting role as Ella Mae Farmer, a statistics clerk for the Washington, D.C. police department, on the CBS crime drama The District. She guest-starred in episodes of Gimme A Break!, L.A. Law, Law & Order, The Days and Nights of Molly Dodd, Homicide: Life on the Street, and Thirtysomething.”
In 1997, for her first Broadway appearance in ten years, Lynne Thigpen played Dr. Judith Kaufman, a half-Black, half-Jewish feminist in Wasserstein’s An American Daughter. She made her entrance on stage soaking wet, her character having just attempted to drown herself in a river. Her performance won the year’s Tony Award® for Best Supporting Actress, and she played the role again in 2000 in a movie made for TV. She was again nominated for an Obie for her work in Jar the Floor, presented in 1999 by the Second Stage Theater.

Thigpen died of a cerebral hemorrhage on March 12, 2003, in her Marina del Rey, California, home. Thigpen had been complaining of headaches during the final days of her life. Drugs and foul play were ruled out by the coroner’s autopsy, which found “acute cardiac dysfunction, non-traumatic systemic and spontaneous intraventricular hemorrhage and hemorrhage in the brain.” She was entombed next to her parents at Elmhurst Cemetery in her hometown of Joliet, Illinois. When Thigpen died, the third season finale of The District had a tribute to her character, Ella Mae Farmer. Thigpen’s death led to a four-year hiatus of Bear in the Big Blue House. A planned film version of Bear was also put on hold. Two years after Thigpen’s death, Tara Mooney interviewed with Bear star Ray D’Arcy on Today FM stated: “The crew’s hearts just weren’t in it anymore”. Thigpen’s friends and family established a non-profit foundation, The Lynne Thigpen – Bobo Lewis Foundation, to help young actors and actresses learn how to survive and succeed in New York theater and to mentor the next generation of Broadway stars.
Thigpen was posthumously nominated for a Daytime Emmy Award for voicing Luna the moon in Bear in the Big Blue House, but lost to Jeff Corwin. Her final film, Anger Management, was dedicated in her memory. Also, an elementary school in her hometown was named in her honor.
