One way the comics writers explained this discrepancy was to present the characters as “real” cartoon characters who are employed by Disney as actors. Walter J. Ong in his cultural research of Mickey Mouse and Americanism also agreed with this opinion. In short, characters are more human-likely but less animal features in their characteristics. This understanding of the characters leading separate lives was welcomed by Walt Disney who when asked whether or not Mickey and Minnie were married, replied that the mice were indeed married in their “private lives”, but that they sometimes appear as boyfriend and girlfriend for “screen purposes. ” Also, in the World War II propaganda film The New Spirit (1942), Donald Duck fills out his income tax and lists his occupation as “actor”, and the film The Three Musketeers (2004) includes a DVD bonus feature of the characters reminiscing on their experience filming the movie.
