Factual error: The character of Dr. Kearn during his court testimony states that one of his first inventions was the plastic bag for margarine which was used to mix the yellow colouring dye-agent into the white coloured margarine. I have found sources that show that Mr. Peters invented that and held the patent. http://www.michiganhistorymag.com/extra/barnett/butterwars.pdf.
