Animator and McCay biographer John Canemaker produced a film in 1974 called "Remembering Winsor McCay", narrated by McCay's animation assistant John Fitzsimmons. Canemaker helped coordinate the first retrospective of McCay's films at the third International Animation Film Festival in 1975 in New York, which led to a film show at the Whitney Museum of American Art in winter 1975–76. Canemaker also wrote a biography in 1987 called "Winsor McCay: His Life and Art". In 2005, a revised and expanded version of the biography was released, which comics scholar Jeet Heer called "far and away the most scholarly and intelligent biography ever written about an American cartoonist". Animation scholar Paul Wells stated, "McCay's influence on the history of animation cannot be understated". Film critic Richard Eder lamented that as an animation pioneer McCay was not able to reach the potential suggested by his work. Eder compared McCay to the Italian primitives of the early Renaissance, highly skilled "in the limited techniques they could command". Heer wrote that McCay's strength was in his visuals, but that his writing and characters were weak.
