Working behind the scenes at Mattel for over fifteen years, Manson graduated as a Toy Design major from Otis College of Art and Design. In his first few years at Mattel he worked in the Games and Puzzles group and Hot Wheels® group. Eventually Manson settled in the 3D Design Group, where his model making and sculpting skills were used by all the departments within Mattel. Manson has a unique job at Mattel, he takes the designs from the Hot Wheels® Design team and translates it to a 3D prototype. Although he has sculpted cars by hand, like the ’70 Plymouth Barracuda and Low Flow for the 2004 line, he now uses FreeForm, a computer modeling program to make 3D models. Since 2007 Manson has been mainly working on Hot Wheels® mainline cars. He has worked on over 500 cars. In addition to modeling cars, Manson has also designed a handful of cars for Hot Wheels® in the Basic Mainline and Adult Collector Lines. These include, 1981 DeLorean DMC-12, all the Back to the Future Time Machines, various Batman vehicles, A Team Van, Mystery Machine, all the Ghostbusters Ecto cars, The Simpsons cars, Snoopy, and others to come. Manson also works on the Hot Wheels Elite Cult Classics Line, bringing his passion for entertainment cars on a larger scale. His projects include vehicles from Back to the Future, Ghostbusters, A Team, Flintstones, Scooby Doo, and other entertainment brands.
