The actress and comedian appeared for three seasons on Nickelodeon’s sketch series and was remembered by former castmates for her humor and creativity.
LOS ANGELES, Calif. — Christy Knowings, an actress and comedian who became known to young television audiences as a cast member of Nickelodeon’s “All That,” has died at age 46, her father and manager have confirmed.
Knowings died Aug. 11 in California. Her father, Charles Dunn, confirmed his daughter’s death to ABC News on Aug. 14, a day after reports of her death began circulating publicly. A manager for Knowings also confirmed her death. A family member told TMZ that Knowings had suffered an asthma attack on Aug. 7, was hospitalized in the Los Angeles area and was placed on life support after the attack left her with brain damage.
According to the family account given to TMZ, Knowings remained on life support until Aug. 11, when her family decided to remove it. She died that night. The reports did not cite a publicly released medical examiner’s determination, and additional medical details surrounding her death had not been made public.
Knowings joined “All That” in 1997 and appeared on the Nickelodeon sketch comedy series for three seasons through 2000. The show featured young performers in recurring characters, parodies and comedy sketches and became one of the network’s defining programs of the era. Knowings worked alongside performers including Kenan Thompson, Kel Mitchell, Amanda Bynes, Lori Beth Denberg, Josh Server and Nick Cannon.
Among Knowings’ recurring roles was Jessica in the “Whateverrr!!!” sketches with Bynes. She also played characters including Penny Lane and Gloria Bankhead. In a 2019 interview with Bustle, Knowings said Gloria Bankhead, an exaggerated homemaking personality she performed during Season 6, was among her favorite characters because it gave her a chance to play a type of role she had not attempted before.
Knowings also reflected on the diversity of the “All That” cast and what it meant to her as a Bronx native with Native American and Afro-Latina heritage. She said performers were able to bring cultural details into their work and have those differences celebrated as part of the show’s comedy. The series helped establish a number of young performers who later continued careers in television, film and comedy.
Her work extended beyond “All That.” Before joining the series, Knowings appeared in “And Now This,” a Nickelodeon sketch-comedy special associated with Rosie O’Donnell. She later appeared in episodes of “Sesame Street” with her twin brother, Chris Knowings. Her screen credits also included the 2009 film “Mother and Child,” and she released the folk song “To the World” in 2020.
Former castmate Kenan Thompson remembered Knowings in a social media tribute after news of her death. Thompson called her “one of the funniest people out here” and sent his love to her family. The two appeared together during the late 1990s run of “All That,” years before Thompson became a longtime cast member of NBC’s “Saturday Night Live.”
Kel Mitchell also paid tribute, describing Knowings as naturally funny, talented and fearless as a comedian. He praised her ability to create memorable characters and said he remained grateful for the laughter and memories they shared as members of the “All That” cast. Josh Server and other people connected to the program also publicly mourned her death.
Al Hill, a manager for Knowings, told ABC News that she was a multitalented performer whose work included singing, acting and dancing. He described her as professional, dedicated and continually creative. The tributes focused on both her comedic work and the relationships she built during a television career that began when she was young.
Knowings’ death came months after the death of another former “All That” cast member, Kianna Underwood, who was killed in a hit-and-run collision in Brooklyn in January. Underwood was 33. Their deaths prompted renewed attention to performers who were part of Nickelodeon’s long-running sketch comedy franchise.
Knowings’ family has not publicly released extensive details about memorial arrangements. Former castmates and colleagues continued sharing remembrances after her death was confirmed, highlighting the characters she created and her years as part of the “All That” ensemble.
