This is one of six Mickey Mouse cartoons that play in the Main Street Cinema at Disneyland.
In this short, this was the first time that Mickey was voiced by Clarence Nash. Walt Disney was traveling in Europe at the time and was unavailable to record his lines for Mickey for this short.
Besides Clarence Nash only voicing Mickey in "The Dognapper" from 1934, he also voiced Mickey in some "American Motors" commercials.
"The Dognapper" from 1934 is the second of three Black & White Cartoons to feature Donald Duck. It was Donald's third film and was the first adventure story to feature both Mickey and Donald.
