 In a July 4, 2004 interview, Norstein said that 25 minutes of "The Overcoat" had been shot.The studio stopped working on the film for nearly a year while Norstein worked to release his two-volume book, "Snow on the Grass", released on August 10, 2008.To this day (at least as of March 2013), Norstein is still working on the film—his ardent perfectionism has earned him the nickname "The Golden Snail".
