At 42 minutes, this is the shortest Disney "feature" to date.
The "Pedro" segment "inspired" the Chilean cartoonist René Ríos Boettiger ("Pepo") to create, in 1949, his most famous character: "Condorito", which became one of the most popular comic strip characters around the world.
The footage of the team boarding the plane was staged after the trip when the decision was made to use home-movie footage as linking material. Disney realized they had no footage of the real boarding, so everyone dressed in the same outfits they left with and shot footage of them leaving the studio and going into the plane.
The shorts that form this movie were originally intended to be released separately, but were combined to form this movie because it had been decided that each short would only be of interest to the people whose country it depicted. Therefore, footage of the Disney team on location in South America was used to make the framing sequence around the original shorts.
The title song for this movie makes a brief appearance in its follow-up "The Three Caballeros" as underscoring.
This was the first Disney Animated feature to be shown in South America before it was screened in the USA.
