Winkless, who was behind the iconic Chucky doll in Child's Play, passed away on 18 July (15) due to complications from a neurological condition which he had suffered from for the past 15 years, according to Make-Up Artist Magazine.

Winkless controlled the demonic doll in the first four instalments of the horror film franchise, and also served as the puppeteer for the Crypt Keeper in U.S. TV series Tales from the Crypt.

He also worked on other films such as Alien 3, Terminator 2: Judgement Day, Death Becomes Her, and on the small screen in The X-Files and Harry and the Hendersons.
