Walt Disney made propaganda films.
Between 1942 and 1945, during the height of World War II, Walt Disney produced a number of animated shorts for the U.S. government and every branch of the military. These films were produced to increase support for the war and boost public morale. Many were intended specifically for servicemen, but were released to the public due to their popularity.
One example, Der Fuehrer’s Face (1943), features Donald Duck working at a factory in Nazi Germany and was created in an effort to sell war bonds.
