Gary Wayne Coleman (born February 8, 1968) is an American actor, best known for his role as Arnold Jackson in the American sitcom Different Strokes (1978–1986).

In the show, he was portraying a child adopted by a wealthy widower. The show was broadcast from 1978 to 1986, and was a huge success.

He became the most popular fixture of the show (enhanced by his character's catchphrase "What'choo talkin' 'bout, Willis?"). At the height of his fame on Diff'rent Strokes, he earned as much as $100,000 per episode.

However, it is estimated he only received a quarter of that after paying his parents, advisers, lawyers, and taxes. He later successfully sued his parents and his ex-advisers for misappropriation of his finances.
