Sherri Lynn Cook, Four Horsemen Toy Design’s prototype painter extraordinaire, stars in this episode of Hanging with the Horsemen. She was a remarkable sport for agreeing to do a round of interviews after working almost round the clock for a week to get Castle Grayskull and a bunch other prototypes ready for New York Toy Fair. The discussion of paint options features Eric Treadaway, H. Eric “Cornboy” Mayse, Shane Dittsworth and more.

MTV visits to get a sneak peek at the prototypes. So this is actually a behind-the-scenes look at MTV’s behind-the-scenes look at the making of Castle Grayskull.

What does it feel like to finally finish up the biggest and most nerve-racking project ever and ship it off to Mattel? Sherri Lynn Cook lets us know in this video, in her inimitable style. Also featuring Jim Preziosi.
