Gary Coleman, the actor who as a child star of the television comedy “Diff’rent Strokes” made “What’choo talkin ’bout, Willis?” a catchphrase of the 1980s, has died. He was 42.
The death was reported by CBS News, citing the Utah Valley Regional Medical Center in Provo, where Mr. Coleman had been hospitalized after an injury.
A diminutive actor who stood at 4 feet eight inches, Mr. Coleman became a star at age 10 for his role on “Diff’rent Strokes.” The show, which had its debut in 1978, cast him as Arnold Jackson, the younger of two children adopted by the millionaire Philip Drummond (played by Conrad Bain). The show ran for eight years on NBC and ABC.
In 1989, Mr. Coleman sued his adopted parents for mismanaging the money he made on the show and won a settlement, but later filed for bankruptcy. He continued to appear in brief film and television roles, often as himself, and often poking fun at his grownup struggles.
