Near the conclusion of the movie, just before Jimmy captures Charlie the duck, there is a Volkswagen Beetle with the license plate OFP 857 and inside the vehicle is a Great Dane. The tag was the very same as Herbie's in The Love Bug (1969), another Disney movie starring Dean Jones that was the first in a series of "Love Bug" films. The dog is the same breed as in The Ugly Dachshund (1966), also starring Dean Jones.
The Million Dollar Duck (1971) is the first of three movies that film critic Gene Siskel walked out on during his professional career. The other two were the horror film Maniac (1980) and the comedy Black Sheep (1996).
The 70th Live-Action film produced by Disney.
