Gary Coleman
Gary Coleman became famous as a child star in the role of Arnold Jackson in sitcom Diff’rent Strokes, where his catchphrase "What’chu talkin’ ’bout, Willis?" made him a television icon.
As an adult, Coleman battled depression and sued his adoptive parents and former advisers as a mismanaged trust fund resulted in him filing for bankruptcy in 1999.
He also struggled with kidney disease – which limited his growth - throughout his life before his death in 2010 at the age of 42 after falling down the stairs at his home in Utah.
