The Iron Man is a 1930 animated short film which was directed by John Foster and Harry Bailey.
[5] The film begins with a male cat walking down the street singing and playing a music box.
He plays there until Farmer Al Falfa, a recurring character in the Aesop series, looks out of his window, and describes the music as "rotten".
Once he is back home and sitting on the stair leading to his front door, the postal service arrives with a package which is delivered via a horse drawn carriage.
This causes the robot to malfunction, by gradually increasing in size, until it is bigger than the Earth.
[1] The film ends with a moral, which is portrayed with a duck and a sleeping Milton Mouse, the only time he is featured in this cartoon.
Milton proceeds to pull at the pole, which results in him falling off the duck and into the water.
The magazine's closing comment is that "a good slapstick, or a short dramatic number will go along well with this".
