In 2000, Lamothe began pre-production on The Political Dr. Seuss, a documentary on the life and "political" works of Theodor Geisel.
In 2004, the documentary aired nationwide on PBS as the season premiere of Independent Lens.
It was subsequently nominated for a George Foster Peabody Award in documentary television.
Starting in 2005, Lamothe spent two years shooting and editing his next documentary, The Call of the Wild, on the self-proclaimed "aesthetic voyager" Christopher McCandless, a filmmaking odyssey that took him through thirty U.S. states, two Canadian provinces, and parts of Mexico.
