Yagher frequently collaborated with puppeteer Brock Winkless on his productions. For example, Winkless performed the puppetry for Chucky in Child's Play and several of its sequels. Yagher and Winkless also worked closely on the visual effects of Honey, I Blew Up the Kid (1992). Yagher directed Hellraiser: Bloodline, but decided to be credited as Alan Smithee after Dimension Films re-edited the film. He heads Kevin Yagher Productions, Inc. Yagher has worked with "Weird Al" Yankovic on a number of occasions. In 1988, Yagher created a fat suit and appliance makeup for Yankovic's "Fat" video, which Yankovic later wore in his concerts while performing the song. A year later, Yagher created prosthetics that gave Yankovic a hypermuscular upper body when parodying Rambo in his film UHF.
