Malcolm-Jamal Warner, known for The Cosby Show, dies at 54 in Costa Rica drowning accident

The Cosby Show alum Malcolm-Jamal Warner has tragically passed away at the age of 54 following an accidental drowning while on a family vacation in Costa Rica. He was swimming when the accident occurred, according to People. Although it is unknown what caused him to drown, the waters in Costa Rica can be dangerous, depending on the specific beach and conditions. While many beaches offer safe swimming, some have strong currents and rip tides that require caution, particularly for inexperienced swimmers.

The actor, best known for his role as Theodore Huxtable on the beloved NBC sitcom, appeared in all eight seasons from 1984 to 1992. At the time, Warner was just a teenager, but his performance earned widespread acclaim, including a nomination for Outstanding Supporting Actor in a Comedy Series at the 1986 Primetime Emmy Awards. Warner is survived by his wife and young daughter, born in 2017. While he occasionally shared glimpses of his family life on social media, he chose to keep their identities private, opting not to publicly reveal their names.

His character, Theo, was based on Bill Cosby’s real-life son, Ennis Cosby, and was portrayed with depth and sensitivity. In the show, Theo is diagnosed with dyslexia after struggling academically during his freshman year at New York University—an arc that resonated with many viewers. Beyond The Cosby Show, Warner carved out a successful and diverse career in both comedy and drama. He starred as Malcolm McGee in the UPN sitcom Malcolm & Eddie (1996–2000) opposite Eddie Griffin, and later headlined BET’s Reed Between the Lines from 2011 to 2015 as Dr. Alex Reed.

His television credits also included recurring roles and guest appearances on shows like Sons of Anarchy, Jeremiah, The Fresh Prince of Bel-Air, and Community. Warner also voiced the Producer character on the educational children’s series The Magic School Bus. Prior to his breakout role, Warner, who was born in New Jersey, attended a performing arts school in New York City. Cosby personally selected Warner to play his son. News of Warner’s sudden death has left fans and colleagues in shock.

'That man gave us one of the greatest scenes in the history of television. I cannot even believe this. I am over here SOBBING! Rest in poetry, Malcolm Jamal Warner,' one fan wrote on X. Another tweeted: 'Rest in power to Malcolm-Jamal Warner (1970–2025), who passed away on July 21, 2025, at age 54 from an accidental drowning. Forever our Theo Huxtable, a symbol of Black excellence, grace, and artistry. Your legacy shines on.'
