Robbie Knott was a special effects coordinator.
Born in Hollywood, Knott attended Hollywood High School and was raised near the Paramount lot, where his mother served as an assistant to legendary costume designer Edith Head.
Knott helped build the giant Animal puppet with a 15-foot head that came crashing through a roof after accidentally ingesting one of Dr. Bunsen's "insta-grow" pills in The Muppet Movie (1979).
Knott's film résumé also included Repo Man (1984), Dances With Wolves (1990), Dante's Peak (1997), Donnie Darko (2001), Stuart Little 2 (2002) and his final credit, For Your Consideration (2006).
Knott worked on numerous mini-series and made-for-TV films, as well as the NBC detective series, Remington Steele.
His career ended as the result of an accident that occurred in 2006 during a visit to Micronesia, when Knott got the bends and became paralyzed from the waist down.
Knott died June 29, 2018, in Portland, Oregon. He was 73.
