This episode used footage from The Italian Job (1969). All of the shots of the three Minis racing the cops are lifted from the movie.
Kelly McClain's voice is obviously, and at times poorly dubbed; it's not certain if it is her voice or that of someone else.
The minis are always shown in Red, White, Blue order, to represent the colors of the United Kingdom.
The title, Thief of Budapest was lifted from the 1940 film The Thief of Bagdad. Both plots are very similar. The main character gets into a pickle; meets a child thief; the two help each other out of said pickle.
